Previous question: How hard could it be to take advangate of the multi-cores.
The first thing is that it depends on what you are starting with. If you have zero code out there, you can come up with a nice design for your program that takes advantage of as many cores as you throw at it. If on the other hand you have large chunks of legacy code that was written in the time of single cores, it may be close to a re-write to fully take advantage of the hardware. In some cases it will be easier in some cases to throw the old code away.
But some of it is imagination, if you can look at a problem and the solution you orginaly came up with, and using your imagination look at the problem at hand in inovative ways, parts of the programs could be re-written to take advantage of the hardware and other parts can be left alone (for the short term). This is an incremental step, you gain X% in one area and little to nothing in another area. The key is to determine what your program spends most of it time doing and re-write/re-design that section of the code for the biggest short-term gains.
I remeber working in assembler and selecting the correct combination of instructions based on their function and the number of CPU cycles it took to execute each instruction. Sometimes a set of 12 instructions was faster than a different set of 8 instructions in accomplishing the same result. Use your imagination and look at the problem from a different angle. If your brain only sees a number of serialized steps, you won't be able to come up with anything that takes advange of the hardware.
What you start with (old code) and your imagination can get you there quicker or slower.
Short answer: It depends.

When you drive to/from Toronto all the time, standard just makes no sense, now that autos are much more efficient.
People do it every day, It does make sense. Everything from VW, to cobalts/G5 to trucks. Small car autos are junk, and do not have the longevity of larger autos , like in trucks. If I ever own a car (not gonna happen.). It will be a handshaker, or nothing at all.

And, by the way, purchasing stocks based on price isn't very smart. I don't understand why you're singleling out Google just because it has a high stock price. It actually works against your point because it's a great stock-arguably better than Apple.
Stock-price is irrelevant, what matter is the market-capitalization. Quite often I see people comparing two companies and saying stuff like "Company A has a shareprice of $50, whereas Company B has a shareprice of $60. Therefore Company B is better".
I guess Berkshire Hathaway is the Capo di Tutti Capi of companies, since their shareprice is over 90.000 dollars!

I've read that even the current MBP supports 4gigs.
Apple just doesn't offer it in their store since the CPU can only address around 3,2gigs (like every other 32bit cpu).
Unfortunately, the current MBP is restricted to about 3.2GB because of the 32bit CPU *AND* the 32bit i945 chipset. Intel won't have a 64bit mobile chipset until they ship Crestline (the i965 mobile chipset for Santa Rosa). So, unless Crestline is ready early and Apple has some sort of exclusive agreement, the updated MBP still will not allow anyone to use more than approximately 3.2GB of RAM.
In a 32bit system, the 32bit CPUs and/or chipsets can address a total memory capacity of 4GB. But this 4GB address window must account for all memory I/O addresses, BIOS/ROM as well as video memory in addition to the actual RAM heap. That is why when you install 4GB of RAM, you essentially miss out on the last 600 to 800 MB. Also why the C2D/Merom iMac systems can only be configured with up to 3GB of RAM. Apple probably figured they didn't need to sell people RAM that they can't use. Some PC vendors still sell 4GB installed into such systems even though it can't all be used because by installing two matched 2GB modules, the dual-channel performance benefits are there, just not the last 800MB.

TBWA really need to step up their game. Lack of a tangible concept ("ooh it's all about the experience") and a truly awful execution especially in such a redux form. Not to mention the badly chosen score and VO.
If you're going to make something as utterly bland and pretentious as this ad is, then at least do it on a grand scale for the sake of audience recall (Chanel 'film' with Nicole Kidman the most vomit-inducing example of this type).
I actually cringed.

I've never in my life voluntarily watched an ad for anything four times in a row. Ever. I watched it, sat with a "wowed" face like I just watched a really good movie, then clicked "replay" three times. G'job. I will agree with others in that the new iPhone ads are a bit sassy, and that's all good and makes you kinda smirk if you have an iPhone, but it has a tinge of disrespectfulness, even though android wouldn't even exist if the iPhone hadn't come out, but slight disrespectfulness nonetheless. This new ad just plays the nice guy method with really, really good camera angles, lighting, and true content illustrating how many miles ahead of the competition they really are. Bravo.

They are fine on my 07 8 cores Mac Pro. Even light encoding is fine...
I also have the terminal going with 6 tabs, each running folding on another machine. I worried about iTunes because I had heard that it took quite a bit of cpu, but not for me it doesn't seem to have any effect on folding.
interesting. well i might get a mac pro someday. my homebuilt machine is a big hassle and i'm not there to work on it. i would rather have a computer that i can fold and use regularly

I think that it's to do with the geo-location on the camera app, as a person would want to immediately launch the camera app and take a picture, without waiting for the GPS to lock on to them.
That is fine; however, not encrypting the data isn't "fine" at all - they should at least try to keep our location secret, or delete the older GPS locations.

Because Apple says "Tape is Dead" doesn't make it true...just like Blu-Ray isn't gone. So that begs the question--is there tape output support (machine interfacing, et al) for FCX?
If you are talking HDCAM SR, the one factory where it was produced is located in Sendai and was destroyed in the recent tsunami. Nobody knows how soon the factory will be back up, but likely no time soon. 10 tapes were recently sold on Ebay for $5000. The general consensus is the recent tragedy will accelerate the death of tape.

Don't like.
Maybe that's neat but that's not pc-centric.
It's easier and more convenient to just drop the app in the trash. :|

Conroe is cooler than G5, which used the same case.Not because they need to now, but because Apple changes enclosures every few years to keep the line looking new and improved like it is on the inside. Core 2 calls for such a design refresh to further distinguish the new from the old and to have thermal envelope specs capable of supporting Kentsfield 4 cores inside next year. ;)

Actually I REALLY hopes its both USB and FW. FW will allow me to toss my OS disk in and force my disk driveless Mac to boot from it in FW mode.
Why not place a FW port where the optical drive is now (i.e. on the right) and then make a super thin optical drive that has a fold out FW plug. No cords to mess with, just fold out and plug in.
If they wanted, they could even add a small display on top of it that could display a single widget.
maybe they would even make a PRO and non-PRO version, PRO having multitouch in the display.
Just thinking out loud. . .

Interesting� after the new GNOME 3.0 release, I'm convinced we will move farther way from the typical menu layout to a more minimalist, more web interactive interface. iOS is probably the closest to that, but I see windows looking more like FireFox 4 for Windows with the Firefox pop down menu and elimination of File, Edit, View etc. at the top. Mac OS 10.8 or 11 will probably follow suit, except have more webOS like functionality, and will converge several apps into 1�

It's not a fancy looking car, in fact it looks easily can be mistaken for any other boring sedan from GM/Ford/Toyota/Honda/Nissan.
Im jealous, im regretting not getting a Subaru Legacy. I got a 2010 Ford Fusion, should have got the legacy for the good looks and the AWD.

Really confused as to why they just didn't skip to Core2.
Supply constraints, and intel is probably selling apple the yonahs cheaper than meroms.

They are expensive - slow, with a lack of hard disc capacity when compared against the new iMacs and existing PowerBooks ( which I'm sure are also about to go Dual Core 2.
