That's a real shame and I hope that improves for you. I am proud that we appear to be more open minded on this side of the pond. I have had plenty of people disagree with me, but we can agree to accept our differences.
I was once pointed to an interesting indication of the difference in culture. In the USA I believe the $1 bill contains the phrase "In God We Trust". In the UK, we have Charles Darwin on our currency! He appears on the �10 note and a recent �2 coin. The �2 coin changes fairly regularly though.
The God thing is mainly just a way to fight communism in people's mind. It works well among with the propaganda that communism takes away your religion and freedom.

Surprised to see this thread come to a grinding hault after only 145 posts. I pledge right here and now to be one of the first to buy a NEW 8-core Dual Clovertown Mac Pro as soon as it becomes available. I will not wait for them to go refrub although I will probably wait for them to come with iLife '07 if they are added to the BTO page before the January 9th SteveNote.
I turn 60 on January 12th. :) Happy Birthday to me it will be. :eek: :D

Kudos for looking for something (seriously) -- I'd argue that it's a bit limited in scope, though:
-Limited to America
-Limited to adults
-Calculating by household, with strictly boolean "yes or no" (not counting multiples)
For example, in my house, we have 4 laptops and 1 desktop machine, but for this survey, it would only be counted as "yes" for both. Actually, it wouldn't be counted at all, since we're in England ;-)

I have to agree there as well. My G5 Quad is one of the nicest computers I've ever owned. Definitely one of the top 3, possibly the best. And that's saying a lot considering the types of PCs and Unix systems I've owned over the years. I've never had one bit of trouble with it and it's still rather powerful compared to what's out there now. Although, I can see why people would want to sell... I've been watching the G5 systems selling on ebay, hoping I could get a deal on another one, but it's not happening. They're going for just as much as a new one did last January. I could probably sell mine (8GB RAM, FX4500, 2x500GB HD) for more than what I paid for it initially.. Very tempting and I may consider that in another month when the 8-core Mac Pros are released. Because while the G5 Quad is an awesome system, the reality is that as soon as all my software goes universal, it becomes obsolete. ...I have no use for Classic or anything that's still PowerPC native. The only software I use that hasn't made the universal/Intel transition is Adobe CS2. And it runs OK as is on my MBP, not great, but at least it's usable and still faster than it was on my older dual G4.
Ouch! You do make an Outstanding Case for that 8 Core MacPro. For Sure. Okay, so maybe I would be tempted to sell my Quad G5. Scary. . ..

Will it support third party codecs?
Does it have an internal flash drive?
Will I be able to order Music, TV shows and Movies using it?
Do I need a separate computer to use it?
So far, I'm not impressed. How's it different than a media extender?
I would rather have seen a mac mini with core 2 duo, better graphics support, an internal 3.5" hard drive, and HDMI.
Outside codecs are doubtful. It'd support it in that if you convert the media that's encoded with the 3rd party codecs to something quicktime can handle.
Flash drive? *why* would that have any benefit. Too small. Very doubtful.
Ordering from it. Maybe. But then if you have 2 machines that it's pulling content from, which machine actually does the payment, downloading and storing of the file(s)?
A seperate computer? Seemingly, any OSX or Windows machine running iTunes will be what the 'iTV' pulls it's content from. So yes.
What's a 'media extender'?
I would love to know if those who are saying they'd rather have a Mac Mini, rather then an iTV (which would approx cost half what the Mini would) have ever used a Tivo or a ReplayTV. It's the interface that makes both of those what they are, the ease of use. It's what MythTV's always battled. Yes, you may be able to buy a Mini and morph it into an iTV, but at half the price, and having to spend the time dealing with it to make it all work, why bother? About the only justification for buying the Mini instead that I can see is if you don't already have a machine that can run iTunes.

Even our PCs are not standalone by that definition, basically needing a Net connection to get much done.

It's funny as I'm sure the world of computing managed to perform quite well as did I with all my many computers, many many MANY years before the internet was around and in use my the public in any real numbers and we could download pictures of naked ladies :eek:
A PC can do anything and everything you want, It's a full computer, not a web browser.

I don't know why it wouldn't. Isn't iTunes basically and interface for Quicktime? I would imagine anything one can play in QT, you can play through this.
All it is is Apple's version of a media extender. I would, however, like an optical drive, but I can't see the price staying at $299 if they add Blu Ray. Otherwise, I think it's a fair price for a quality piece of equipment. Roku's SoundBridge M2000 is $299. For the same price I get to also sent 1080p content to my home theatre. Sign me up.

No, I believe Apple will pop the Core 2 Duo Merom into the iMac. It's supposedly a drop-in replacement for the current Core Duo processor the iMac currently uses.
This will not be an option for Apple. They no longer live in the PPC world, now people can directly compare the specs on any Mac to the specs DELL or other PC vendors are offering.
The iMac is Apple's desktop computer, and currently the only one they offer. As such they will have to spec it as a desktop computer as much as humanly possible, and having a slower CORE 2 Duo than their competitors (when iMacs cost more) will not do them any favours.
Also bear in mind that Conroes are cheaper for apple to buy than Meroms, as well as offering faster clock speeds and more performance. So it wouldn't cost Apple much more, per machine, to put a 2.4Ghz conroe in rather than a 2.0Ghz merom.
The heat issue is also a non-starter. I have a laptop with a 3.2Ghz Pentium 4 in it, which runs a hell of a lot hotter than the Conroes will. Sure it isn't the smallest laptop ever, but it's comparable in size to an iMac, if anything it's slightly thinner. Many laptop venders have said they're putting conroes in their top laptops because of the extra performance, and if they can there's no reason Apple can't fit one into the iMac.
Apple can either put Meroms in the iMac and thus make an over-priced under-performing desktop or redesign the motherboard for Conroe and have a competitive desktop. If they want to continue their recent success with the switch to Intel they cannot afford to be lazy and simply drop a merom into the iMac.
Personally I'm also hoping for the option of a BTO X1800 graphics card. At the least I expect the VRAM on the X1600 to be bumped to 256Mb on all iMacs and for the screens to get a resolution bump. The 17" will get the same screen as the 17' Macbook Pro (1650x1050) and the 20" will get a resolution bump to something closer to True HD (like the cinema displays) which is what professionals will want to work with.
First post, woo!
EDIT: My dream iMac config would be:
17" 1650x1050
2.4Ghz conroe
2Gb RAM (BTO)
750Gb HDD (BTO)
x1800 512Mb (BTO)
And I would be willing to pay quite a bit for it. Fingers crossed apple offers it...

Why are people being defensive and bringing up a few examples like final fantasy 3? These games are not the norm. Look at the top downloads list in the app store to get a good idea of what most games are.
iOS games are fine, but the majority of them really are time wasters. The only real advantage most iOS games have is that they are much cheaper than on portable systems or console games.
For most popular games though the experience isn't nearly good enough. The most popular games on consoles are FPS, Racing games, and Sports. Without physical buttons iOS can't compete with the same genres of games. iOS is better at puzzle games where touching is preferable to moving a mouse/controller, and can be fine on RPG games especially if they are turn based.
Real racing can be fun, but enthusiasts buy steering wheels to play gran turismo and forza. It's just not the same.

so much for the no malware on macs myth :D
funny how the apple fanboys are getting all defensive :rolleyes:
Just look at the monster negative vote rating against anyone who ever criticizes Apple or anything remotely related (i.e. typical fanboy mass attack; they can't let blasphemy just go bye :D ). Frankly, I'm starting to think the lower the number on your post in most threads on such topics, the SMARTER you are. I know I usually give props to all the messages with the lowest scores since they are usually the only ones to tell the truth (kind of like listening to the Tea Party for advice; most are clueless fanatics and not much else).
I mean just look at the number for your post. You told the 100% gospel truth. There IS malware for the Mac (even if it's not very dangerous) and pointed out the truth that most fanboys on here are getting completely bent out of shape and acting immature with their sarcasm. You were at -20 right before I hit reply in a thread where the average number is +/-2.
If someone can find me a set of Macintosh 'fanboy free' forums (as in fanboy accounts are deleted once recognized as such, themselves being a form of spam IMO), I'd love to know about it. It'd eliminate 95% of the total worthless fluff. Just think how much extra time one would have to do other things instead of wading through a cesspool of useless junk every day. ;)
Why do Mac users get less infections? My belief is that the users may be of higher quality, ONLY because of the computers niche-like nature and most Mac users are dedicated, technologically knowledgable.
You must not get around much. Most Mac users I see everyday are technological neophytes. The Mac is designed to attract non-tech users so this shouldn't be a shock or anything. The difference I see is that most Mac users THINK they know 10-50x more than they actually do. Yes there are some very knowledgeable Mac users out there, but they are not in the majority by a long shot, IMO. The sheer volumes of drone-like fanboys on these forums ought to give you a clue just how bad it really is.

So if you're sticking at 4.1.0 and they aren't monitoring, then they should be monitoring 3.x even less, no?
All the more reason for me to stick with 3.1.3 on my 3G.

Wow... was multi-tasking supported that early, or did we not get that until 4.0. It's early here in Florida and I can't remember.
But hey, if its working for you... go with it!

Apple sells music only to sell iPods. People are locked into their iPods because their iTunes music can't be played on any other brand of player.
And if you look at the number of iPods sold compared to the number of ITMS songs sold, it is plainly obvious this statement is pure bull.

In my opinion Lego Harry Potter on the iPad was the definitive version on any platform, and superb on through the 2 onto the big screen.

So what is this thing, anyway? .... I've seen no indication if it does or does not have a hard drive.
Who cares if it has a hard drive if you hve at least one other computer on your network you can "share" a folder and then the iTV will act as if it does have a hard drive..
My guess.. iTV is a mini with no optical drive, a very small hard drive (to store the software and hold a small local cache) and an Intel video chip that can do HD formats
I can envision a third party device that has the same form factor as the iTV so it could stack on or under it. This gadget would have a cable TV tunner and digitizer and connect to the iTV via USB. This way cable TV shows could be saved automatically to your iTunes library where they would show up in the Front Row menu. I doubt Apple would offer this but I'll bet someoe else will.
Is the Ethernet port 100BaseT or Gigabit? How many iTVs can you have on one network. Can a Mac Pro stream 2, 10 or 20 video streams. I can see this used in an educational setting. A school could keep large numbers of recored lectures on a server. Students could water on big screens, thier PC/Mac or on an iPod. There are uses for this other than to feed the typical brain dead TV zombie

Now that we know the real truth about the "better standard FPU", I thought it was time to shed some light on non vectorized G4 integer processing.
It still does 200,000,000 calculations, but this time I'm multiplying ints.
Motorola 7455 G4@800Mhz: 9 seconds (Native)
IBM 750FX G3@700Mhz: 7 seconds (Native)
Intel P4@2600Mhz 2 seconds (Java)
PowerPC 7455 integer processing is consierabley better than floating point (obviously less work doing ints), but still less per cycle than the Pentium 4.
Very intresting the G4 looses both floating point and integer to the IBM chip, at a 100MHz clock disadvantage.
I'm still waiting to see that "better standard FPU" in the G4. It seems the G4 is absolutely useless unless you are fortunate to have vectorized (AltiVec) code.
Alex, yeah, the native version was compiled under 3.1. It really is interesting to note that despite the 750FX's 100MHz clock disadvantage, it is able to outperform it by 22%. Since there is a 13% difference in clock speed, and if clocks were equal, the 750FX is technically 25% more efficient in scalar integer. I should also re-emphasize that I never bothered compiling the test natively for x86, I left it java, so it's not out of the question the P4 could do this in 1 second - and that is *NOT* using any vector libraries, just plain old integer math.
I've found some documentation on the Altivec C programming interface, and this weekend I'm going to make a first attempt at vectorizing it. The integer test should be no problem, but my FPMathTest app that did square roots will be more difficult. With Altivec, there is not recognized double precision floating point, so this complicates doing square roots. If you want more accurate, precision square roots, you have to do Newton Raphson refinement. In other words more ************ you have to go through. I believe in SSE2 you have double precision floating point ops, and if you were to vectorize it, you wouldn't have to compensate for this.
Another theory as to why the P4 is scoring so good is because if I'm not mistaking (and I'm not), the P4's ALU runs at double its clock. So in my case, 5.6GHz. I'm sure this relates to the issue.
I don't know how true this is, but I wouldn't be suprised if there is some truth to it, surely some food for thought:

The G4 was just a hacked-up G3 with AltiVec and an FPU (floating point unit) borrowed from the outdated 604
If this is the case, then no wonder why we are getting these abysmal scores, and no wonder why a 400mhz Celeron can nearly equal it, and no wonder why the 750FX can outperform it (different company, different fpu)
What you are saying makes a lot of sense. Now that I think about, I too recall reading this somewhere.
Now that we know the real truth about the "better standard FPU", I thought it was time to shed some light on non vectorized G4 integer processing.
It still does 200,000,000 calculations, but this time I'm multiplying ints.
Motorola 7455 G4@800Mhz: 9 seconds (Native)
IBM 750FX G3@700Mhz: 7 seconds (Native)
Intel P4@2600Mhz 2 seconds (Java)
PowerPC 7455 integer processing is consierabley better than floating point (obviously less work doing ints), but still less per cycle than the Pentium 4.
Very intresting the G4 looses both floating point and integer to the IBM chip, at a 100MHz clock disadvantage.
I'm still waiting to see that "better standard FPU" in the G4. It seems the G4 is absolutely useless unless you are fortunate to have vectorized (AltiVec) code.
Alex, yeah, the native version was compiled under 3.1. It really is interesting to note that despite the 750FX's 100MHz clock disadvantage, it is able to outperform it by 22%. Since there is a 13% difference in clock speed, and if clocks were equal, the 750FX is technically 25% more efficient in scalar integer. I should also re-emphasize that I never bothered compiling the test natively for x86, I left it java, so it's not out of the question the P4 could do this in 1 second - and that is *NOT* using any vector libraries, just plain old integer math.
I've found some documentation on the Altivec C programming interface, and this weekend I'm going to make a first attempt at vectorizing it. The integer test should be no problem, but my FPMathTest app that did square roots will be more difficult. With Altivec, there is not recognized double precision floating point, so this complicates doing square roots. If you want more accurate, precision square roots, you have to do Newton Raphson refinement. In other words more ************ you have to go through. I believe in SSE2 you have double precision floating point ops, and if you were to vectorize it, you wouldn't have to compensate for this.
Another theory as to why the P4 is scoring so good is because if I'm not mistaking (and I'm not), the P4's ALU runs at double its clock. So in my case, 5.6GHz. I'm sure this relates to the issue.
I don't know how true this is, but I wouldn't be suprised if there is some truth to it, surely some food for thought:
