seriously though, how hard is it to get a program to multi-thread? (if thats the right term; being a complete programming novice, i've no idea)
That really depends on the program, on how "parallelizable" the application is.
The simplest way to think of it is like this: Let's say you have a program that first has to calculate A. Then, when it's done that, it uses the result of A to calculate B. Then, when it's done that, uses the result of B to calculate C, then C to D, and so on. That's a *serial* problem there. The calculation of B can't begin until A is done, so it doesn't matter how many processors you have running, all computation is held up on one spot.
On the other hand, let's say you have an application that needs to calculate A, B, C and D, but those four values are not dependent on each other at all. In that case, you can use four processors at the same time, to calculate all four values at the same time.
Think of it like baking a cake. You can't start putting on the icing until the cake is done baking. And you can't start baking the cake until the ingredients are all mixed together. But you can have people simultaneously getting out and measuring the ingredients.
So that problem is partially parallelizable, but the majority of its workload is a serial process.
Some software applications, just by their very nature, will never be able to do anything useful with multiple processors.

Typical. Are they 2.33 and 2.66GHz models Aiden? Got links?
SideNote: The Madonna Concert in HD on NBC tonight is groundbreaking broadcast television. One of the most amazing telecasts I have ever seen-heard. I am a huge Madonna fan though. :D Tony Bennett's special last night also on NBC was an amazing HD composition as well.
I just had a (very) brief look, Dell seems to be offering Cloverton in their Precision workstations, but only the low-end E5320 1.86Ghz model:
http://configure.us.dell.com/dellstore/config.aspx?c=us&cs=555&l=en&oc=MLB1727&s=biz
I imagine that Apple probably won't use this model in the Mac Pro or Xserves, and are probably waiting on the faster versions to be available in greater quantities, as it seems that they might be in short supply if Dell's only offering the slowest version.

if you look at the codenames for many products, and I'm talking about way back to the apple II days, air seems more like a codename for a product than the product name itself. Maybe they will announce something like they did with the "iTV" and refer to it by its codename, because they don't have a name yet and it's not even out for official release yet.
Stop making sense. It's not welcome here.
You need to be more fanboy-ish. :D

This is potentially great news...
I had a stock ATI 5850 in the Mac Pro for a while, OS X didn't like it but Windows ran it perfectly... in the end bit the bullet and bought a 5870 Mac edition for about twice the market value of a standard PC card!
Great decision though, the Mac now runs about 20 times faster... not just games either... the whole UI is great now (I guess thanks to OpenCL et al)
...and whoever decided the GT120 was a good card for a Mac Pro needs to be shot!

wouldn't swapping a conroe chip in be an option? just go to Fry's and buy the chip then.
No, the Conroe and Merom are not, as they call it, pin-compatible. The Yonah and Merom are, by the way. So yeah, it makes sense for Apple to go with the Merom, but that doesn't mean I like it one bit.
EDIT: Sorry, roland.g, you beat me to it.

I really don't car about close racing in F1 as I would just prefer teams the engineering to be unregulated (except for safety). My opinion I believe is in the minority.
For road based cars, I want close racing. I really do agree that ALMS and LeMans are fantastic, as well as touring cars. If I ever go (which I plan on doing sooner than later) I might have to try to say "hi" to you. I much enjoy your photos. Being near the pits would be the cats meow for me. Its the work done behind the scenes and fuel/tire changes that make me feel as if I just drank 3 Chai chargers:D
The US GP in Austin is still supposed to take place correct?

Lets see how they make this happen, movies are big downloads (or so im told :p ;) ) people wont like spending a lot of time downloading a file only for it to become completely useless a while later. But if it increases the content in the iTMS then so be it!

I'm hoping for a MPB with: Core 2 Duo up to 2.33 Ghz - Flash boot (NAND memory) - better GPU, ATI launched her x1800 mobile GPU march 2006 - 802.11n - more ram capacity - firewire 800 and faster super drive.
But Im afread I have to wait untill january for this master piece of mobile technology. :(
The X1800 is a monster though...... I think the only thing you can even find it in is some of those high-end 17" gaming behemoth laptops. I can't see any possible way they'd fit it into the 15 or 17" MBP.

I know this is venturing into iOS territory, but the single feature that would drive Classic well into the future for me is AirPlay. No other touchscreen BS; keep it rugged, keep it click wheel, just 160+GB of your fixed and lovingly maintained library, in your hand, poised to beam to the big stereo.
Yeah.
Yeah.

hey go ahead and start one if you want. i know what you mean though. i never thought i'd get to 1 million points when i first started. now i'm almost at 7 million!
Hehehe no it's fine, I will post it in this thread however ;)
Just realised that 1 million is very possible for me.

After watching the ad 3 times, I *think* I like it. It treads just the right sign of 'schmoltzy' without going too far over. It (the device) looks gorgeous too, from a purely personal view.
It hasn't won me over (iPad v Playbook), but there's not doubting its a good ad.

Per your comment below, I think you might be misunderstanding Crossfire.
The MP does have an upgrade option to include two 5770's that will allow you to drive up to six displays. This is great but this should not be confused with crossfire.
If they were set up in crossfire you would only be able to drive 3 monitors as you would be limited to the output of your primary card. The second card acts as extra processing load for the primary card while set up in crossfire. Additionally if they were setup in crossfire you would see a bridge between the two cards.
As far as i know Apple has never supported crossfire or sli. They have however supported multi gpus in one machine.
Well then, Apple is gonna confuse alot of people with the 5770 crossfire MP upgrade. Look it up folks, crossfire is supported

Two *major* bugs:
1) TextEdit crashes on launch (tried trashing the prefs file - nothing)
2) cmd+left/right no longer goes to the start/end of the line :O wtf!
Anyone else experiencing these?

I like the UK. B&O have their entire product range here, wheras they don't in Australia...
Their store in Melbourne CBD is pretty comprehensive, i don't know what they are missing but im pretty sure they could get it for you if you wanted it

Does it affect the iPod touch itself?
Not at all. It's pretty easy to clean too, just use a damp paper towel.
Another thing I noticed, if anyone still has their 1st generation iPod Touch's stand (the little plastic default one that came with it), it works pretty well on the 4th generation iPod with the Grip Vue case.

You never know. The same thing happened with the fat Nano rumor:
There's not even a tiny chance that Apple would release something that daft.

I think a lot of you are expecting way too much on the "iTV" and will be very disappointed when it gets released.
What do I see the iTV for? Streaming media, a glorified IP TV box, an easier way to bring the iPod to the living room. I really don't see it doing anything else. I'm hoping that I'm wrong.

Which would be totally fine with me, I just NEED HD content. On that note...I wonder if I could transfer my standard def purchases into HD ones.:confused:

Wow, that is a shocker.
The U.S. Congress passed a law to prohibit any attempt to assassinate any foreign leader.
Why, I don't know, but there it is. :confused:
I saw on CNN that our intention was to cripple the opposition, and if it so happens that Qaddafi is in that building then that is purely coincidental. :rolleyes: :D
Isn't it funny that the world acts like a bunch of 10-year-olds when it comes to war? Did I say funny? I meant sad, dangerous, and catastrophic.

While I agree with your thought process behind you post that Apple is targeting a different audience. That target audience is dwindling very quickly as Apple's prices increase in comparison to the rest of the market.
I'm sorry, why is their target audience dwindling? Are there fewer professional graphics artists out there? Are there fewer people that demand professional color accuracy today then 5 or 10 years ago? I would be interested in a link to some research, because common sense to me says that day by day that market can only be growing.
Now I haven't done the research, but perhaps you can find a similarly specced 20" wide S-IPS LCD so we can see how out of whack Apple's prices are.
