First of all, you assume that it is possible to make "one big core equal in processing power to the 8 cores". I don't think it is possible to do this (at least not with the x86 architecture using today's technology.)
But assuming such a chip exists, the answer depends on what kind of efficiency you're thinking of.
If you mean computational efficiency (meaning the most useful processing per clock-tick), then a single big core will do better. This is because single-threaded apps will be able to use the full power (whereas multiple threads are needed to take advantagte of multiple cores.) Also, the operating system can get rid of the overhead that is needed to keep software running on the multiple cores from stepping on each other.
If you mean energy efficiency (amount of processing per watt of electricity consumed), then it could go either way, depending on how the chips are made. But given today's manufacturing processes and the non-linear power curve that we see as clock speeds are increased, the multiple-core solution will almost definitely use less power.
I remember hearing about how it is possible to make multiple cores act like one (Idon't remember where I heard this). Anyways, whether 8 cores acting separately or together like 1 big processor has an advantage depends on the program you use. If the program is multi-threaded, then the cores acting separately might have the advantage while single threaded apps will have an advantage if the cores are acting like one. However, many apps today won't see that much improvement either way (like a simple calculator, or solitare and word processing).

Uh, except I said "lots of professionals" and then you claimed I meant "professionals that I know" and then you acknowledged that it's not just professionals that I know.
Yes, I agreed there are professionals, but not LOTS of professionals. You don't know, cause... you don't know them, and neither do I. So these "lots" outside of your field of view may or may not be looking to switch. You see the difference, yes?

most of the new stuff out sucks.
I agree. I am SICK AND TIRED of the music industry blaming lack of sales on piracy! Piracy is actually down from what it was a couple years ago but they still claim profits are worse now than ever.
Maybe if they didnt put out the same cookie-cutter bands year after year, album after album, put out albums with 9 good tracks instead on 1 good one with 15 filler pieces of crap sales might improve!

Isn't this hypocritical since Apple has been known to do this in their retail stores too?
Sources? Evidence? Easy to make cheap accusations, much harder to prove them.

Android is the next windows. So many drivers, so much requirements, so many configurations, so little memory. Fortunately Apple's provided a better sandbox.
I really do think that Android/Windows is a good comparison. At least, in terms of getting Android out there on as many different phones as possible. And while that certainly worked, it doesn't really mean that Android is the best OS because it is slightly different depending on the hardware it is on. Which brings up a clear advantage of iOS: It's written specifically for the hardware it is on.

all the pictures i've seen of leopard show a unified interface :D
Safari appears to be brushed metal. Go here (http://www.apple.com/macosx/leopard/dashboard.html) and go to about 1/6 of the way through.

I would have thought that the Final Cut Pro benchmark would have really blown away the G5 - not so much, right?
Awesome on FileMaker and I can't wait to see how this stuff runs Adobe PS Natively.
The vague manner in which they described the test, it seems like this may have been more of an I/O problem than a processing one. Can't say for sure.

The time machine features are just like salvage files on our old netware servers (before we "upgraded" to win2k3 with the quite embarressingly bad volume shadow copies). Obviously time machine is prettier, but the way it worked on netware was that all files whenever they are overwritten or deleted sit inbetween space. You can go into filer or use the right click menu to go back to previous versions of files unless you have purged them. This feature would turn off when you get down to 10% free space remaining.
If time machine lets you preview the contents of documents before you restore them, instead of going restore... is it that one? nope, try this one? nope... ah here we go found it. then hot damm thats a slick new feature

It seems like a preponderance of the issues people have are with the notebooks.
Do you think it could be because Apple has the thinnest laptops on the market which means they sacrifice build quality and heat management?
When I looked at the innards of an iBook G3 it was basically "a mess" in there...nothing looked modular like you would see inside the new Mac pro.
Apple doesn't has the thinnest laptops on the market.

Unless, like I posted earlier, the iPad app functions as a UI for the main application over the network. The Mac (or cluster of macs) takes care of the heavy lifting, and the iPad is used to make edits remotely, and broadcast to HDTV's.
AirPlay & AirEdit.
If you had a cluster of Mac Pro's using thunderbolt (or whatever...ethernet, fibre, etc) to talk to each other, and you used the iPad as a remote UI, you could edit, compress, and broadcast from anywhere.
Apple has all the pieces in place to do this. AirPlay, AppleTV, iPad, iTunes as a media hub for all the devices to communicate, Qmaster, etc...
This has been a long time coming. I remember in 2006-2007 hearing rumors that Apple was working on a tablet like controller for logic. It was to be used to edit the timeline, or act as a virtual mixer, etc. This has been brewing for years, and I think it's almost a reality.
Avid demo'd basically this last year at NAB. IIRC all the media was on servers in Virginia and the presenter did the demonstration on a laptop using a web app.

What's funny is that even if new MacBooks and MacBook Pros were released tomorrow with the newer Merom chip, 90% of you folks in here wouldn't notice a difference in your daily computing. You would not say "OMG, this 64 bit processing and extra .16Ghz speed is AWESOME!!! I can't BELIEVE I lived without this for so long!!!" You wouldn't even notice unless someone told you.

I goofed. I misinterpreted what Lee said about sodomy. He said that not all homosexuals engage in sodomy. I thought he thought homosexual sex was not sodomy. Unfortunately, too often, when I'm impulsive, I misinterpret what others write.
I don't look down on anyone here. I didn't look down on anyone here. I'm sorry I gave the impression that I did that. I'm sorry I've written insultingly, too. I didn't mean to do that.
Sadly, I sometimes do react emotionally when I should react rationally instead. And I do need to try harder to comprehend what others say.
Fair enough. Now let's move along. ;)

Samsung can say all they want about their products. There are the following glaring issues:
1. Has anyone realize how much less Samsung's profit margins will be on the Galaxy Tab versus the iPad2? (ie. Apple retains a high profitability based on inhouse product development rather than contracting to third parties like other hardware developers)
2. Given what I perceive to be an extremely small profit margin, I find it difficult from an investor standpoint to endorse Samsung's business model.
3. It is next to impossible from a longterm business perspective that Samsung can price match Apple in this respect. It's an unsustainable business practice.
You obviously don't know much about samsung. Samsung makes RAM and CPU that apple uses in iphone/ipad. Possibly LCD too. A4 was definitely made by samsung. It's pretty certain A5 is also made by samsung, despite rumors TSMC will make them for apple.
Samsung being samsung, they can match Apple in price in tablet forever (well maybe not forever but for a long time) even without making much profit (not that they would do it). Samsung is HUGE. They have plenty of other stuff they can sell with profit.

Appleinsider is saying that it can be used for both at your choice, but you have to go buy it and put it in. Not a add on to ordering.
So excited... How come no FW800 infront? thats a little crazy no?
Just think if this was apple leaking out information when really its a completely different design. Since they're was that leaking lawsuit and all. Wouldn't it be great if the figured out the sources leaking internaly and made those sources give Appleinsider false information.
Come August 7th, It's completely different... (oh just woke up from my dream.)

MS Windows has about 95% of the world market...doesn't mean the technology is better.:)
A phone that works in most of the world is better for many of us. Who wants a phone that won't work in Europe for instance? Last I checked, my Mac works here just fine.

Are you smoking something? Sure the IGP used in SB 13" MBP might get some fudged numbers by those who report for Apple, but you think the ULV SB IGP is going to even compare to the 320m on any level??? Huh? You are far smarter than that.
So what you are saying is, AnandTech manipulated their own benchmarks so Intel HD 3000 would look better than 320M? That's how I interpret your post. If all you want to believe is those Windows scores which are irrelevant when it comes to OS X, be my guest.
I didn't say the ULV IGP will be anything close to 320M, but just because it's 50% worse under Windows doesn't mean that it will be as bad in OS X. I'm pretty sure you even said that the benchmarks under Windows are not relevant when the first preview of SB was published.

There is no telling how much Inventory RadioShack is going to actually receive. My buddy told me my pre-order, I mean reserve was the first one to go through in the district. Our district here was able to generate 60 PINs he was told by the DM. Not I don't believe anything RadioShack says and don't expect them to receive all 60 of the phones. I just pray that his store receives at least one iPhone 4 so I can have mine.

When I watched basketball performances, it was from "The Shack." When I was 12, I had my porno hidden in "The Shack." And when I was 15 and in the Boy Scouts and I went camping/boating, I took a crap in "The Shack." But, when I was 16 and built a home-made rocket, I got my parts from "RADIO SHACK."
