No I think you are confused. :) I meant "Is having more cores, lets say 8, more efficient than one big core equal in processing power to the 8 cores?"
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 think they'll be a long way off getting money from every iPod sold. For a start its such an illogical thing to ask for (Did the music companies ask for money for every CD player or Tape Recorder sold? Nope), plus I suspect the main reason that Microsoft agreed to pay money in the first place is that they needed to get the music labels on board to boost the Zune Music Store, Microsoft was in the weaker position here and I believe the labels exploited that weakness.
If the labels were to go to Apple and demand a royalty on every iPod and threatening to pull their catalogue if they didn't get it, they would actually come off worse than Apple in terms of lost revenue and it's because of this I reckon they haven't a chance...

This seems to me to be good news in 2 ways:
1. It makes a few foolish people think twice about purchasing an iPad 2, so I can get mine a little sooner.
2. It puts the wind up Apple's behind and they work that little bit harder to get us the iPad 3 with the ultra HD display or iPad 2 Retina Christmas Special or whatever else they might call it.
The iPhone 4 display "changed everything" as Apple like to say, and the sooner they get that thing on the iPad, the better. Then my humdrum life will finally be complete.

Seems the tablet competition is really between google's android, webOS and windows 7. Apple already took what it can take. Others are fighting for the leftovers.

I'll chime in and try to help alleviate your quandary. I would take it back. You've got a narrow window of opportunity to take it back, and we're just a few days away from an event that will likely harold the release of a new iMac. Even if you wanted to keep this model, if you take it back and then buy it after the release of the new one, you'll likely be able to get it at a fairly discounted price. So, that's what you have to weigh against having a computer to play with for the next couple of weeks...Point. You will be able to repurchase as refurbished - which you could have done already BTW - for the same as what you will get back. Refurbished is same as new with new warranty but lower price. Core 2 Duo iMac may be an entirely new design. It's not necessarily going to be just a tweak. I wouldn't risk keeping the one you bought.
We're not saying it will be out after WWDC. We're saying it is DUE by September.

Point is, without an IR sensor in the display, you wouldn't have the OPTION of hiding the computer away.
Yes, but just my opinion, Apple needs to get over this 'Only new computers get FrontRow' crap and provide a USB repeater. Geez, people aren't buying new computers to get FrontRow, they're buying them to get Intel, so providing FrontRow to legacy systems isn't going to cripple sales! The only error in that opinion might be the mini, both the G4 and Intel minis are so crippled, neither makes any sense in a home theater setting but, providing a USB repeater for the G4 mini might effect a few Intel mini sales.

No indeed, it's not. Intel forced the whole OEM industry to use their IGP, not just Apple. ;)
No matter how you slice it, for some applications, IGPs make sense. Intel cut out the competence from that market with their shenanigans. And now the consumers pays for it with sub-par graphics processors.
haha clever, i'm not really arguing with you, i rather agree with what you are saying, i just don't put the blame on intel. Sure the whole debacle may have pursuaded apple to just use the IGP, but i think it's more of apples decision to make things as thin as possible that left out a dedicated gpu in favor of the IGP.
If apple really didn't want their customers to have to use intels graphics, they could have easily gotten around this, they just may have had to do some design changes they weren't willing to make. just my .02 but either way i wouldn't consider the 320m of old to be very high end either. If you are looking to game or need a high end graphics card you should stick to desktop, perhaps even PC over mac.

Not sure I believe the rumors, but as long as my 3G still works, I'll wait. $200 every 3 years is better than $200 every 2 years.
That is why you sell your iphone every year and it does not cost you to upgrade. ATT basically allows you to upgrade at the lowest price every year.
Its all about timing.

True (today anyway; in the NT era they were indeed separate platforms though. Which brings me to my next point..)
I think you're a bit arse-about-face there. Someone else has already pointed out the differences between XP and Windows 2003 aren't trivial, so I won't go into that. However, if you're sufficient vintage, you should remember the "outrage" when someone demonstrated that you could turn NT 4 Workstation into NT 4 Server (including the boot and login screens) just by changing a few Registry settings (although the part that usually doesn't get said is that those Registry settings then triggered a whole range of different tuning settings for the scheduler, memory management, etc). NT 3.5 & 3.51 were the same, and IIRC, NT 3.1 didn't even have a "Server" version.

I wonder what it would be like to go through life looking for racism around every corner? Constantly seeing the world in these glasses would have to be very tiresome and frustrating. Pretty sad really. People need to stop thinking about themselves and others as being members of groups, and start thinking of everyone as individuals. We're a society of individuals, we get our rights and our liberties as individuals, not because we're part of group A or group B.
If liberals would stop 'crying wolf' ('claiming racism') at every corner, we might actually take them seriously and help out when there's actual evidence.

The most interesting thing here is how some people hang on every word over updates to the MacBook Air line.
Some won't touch it without a Sandy Bridge update, others want it left alone to save the NVIDIA graphics.
From dated chips, future proofing, when to buy, getting in at the right time and on and on ...
What gives?
In 90% of the tasks the average MacBook Air owner does are they really going to notice it either way?
Future proofing/saving a few hundred dollars ... there is no such thing ... just look back at the electronics you purchased in the past... how has 'future proofing' worked for you so far? lol
Like it. Buy it. Enjoy it.
People who keep waiting for the next rev will never buy a computer. The "right time to buy" is probably not until the Macbook Air has Skymont in 2015. :p

Scheisse (http://thecaucus.blogs.nytimes.com/2011/04/27/obamas-long-form-birth-certificate-released/?hp)
Mr. Trump claimed credit for forcing Mr. Obama’s hand, saying that “I feel I’ve accomplished something really, really important.” But he said the document released Wednesday would have to be examined for authenticity.
On one hand I think releasing the full certificate should not have happened at this point in time as the dumb ass in the quote above is trying to take credit for forcing the release and only stupid, crazy, and racist people were asking birther questions. And now they all look sane and can claim sanity.
But, now that this long form certificate is out the President can say "Here is what you wanted and now can we move on with business" and if the birthers still question the certificate the President can show, point and claim that it was settled long ago.

You know, Sony and Nintendo are just *SO* behind the curve with next gen gaming systems.
Microsoft has had it's XBox 360 out for MONTHS, while Sony and Nintendo gamers are lagging behind, barely able to function on their PS2s and GameCubes.
If Sony and Nintendo don't release the PS3 and Wii, respectively, in the next week, they'll be the laughing stocks of the industry. There's no excuse for them to release their next gen gaming systems a year after their competitor.
I'm going to hold my breath until I turn blue if I don't get what I want, because I'm childish like that.
Although Sony's PS3 is an overpriced beast with BlueRay support, the nex Nintendo console (which can play old school games) seems promising. As for the Core 2 Duo, personally I don't really care one bit when it comes to a "consumer" grade laptop. Any 64-bit software will work on a 32-bit platform, so I'm fine. Leopard is backwards compatible, so great! If the Merom chips are more energy efficient, that seems promising, but my fridge and TV consume more power, so I don't care. Presently Dell does offer core 2 duo processing chips, but only in their $2,500-3,000 laptop systems. I'm still looking around for laptops that range around low-end MBP and MB prices that have C2D and I haven't found any yet. But since the XPS systems have Core 2 Duo installed, I'm sure the first macs notebooks to see them will be the pros first. But seeing as how my macbooks is presently in the shop for random shut down syndrome, I'm more concerned with a working machine than a machine with a slight efficiency advantage.

I keep reading stuff like this. I don't think Time Machine works with the reagular harddrive. You have to use it with an external drive.
Depends on what threat you want to protect yourself from. On Tiger the trash can protects against acidental deletes and does a usfull job. Time Machine on one drive would act like a nicer, automated trash can and might even replace the trash can. In fact I don't se a need for the trash anymore.
If a user adds a second drive he still gets the effect of the automatic trash can but now can survie a disk smoking. Wat reains to be seen is how configurable this thing is. Can he backup to a server over the Internet AND to his external drive at the same time. What if you are using a RAID? can you back that up to a second RAID? Who backs up the backup server? What is to prevent a "backup cycle" so where one small change fills up every disk on the network? That would be if "A" backed or "B" and "B" backed up "A". Does the system detect longer cycles?? How?

Some of them do but not sure do all of them. I've got several nice rides from those series but they are mainly from higher level series.

Went down to Radio Shack today. They are doing a trade in but you're never gonna get the max price they offer unless it's out of the box new. My 3gs has normal wear over the year so they will only give 230 for it.
And I have a feeling trading in prices will drop when the iPhone 4 drops.
Yeah it sucks because we have no way of knowing if the trade in values will drop on launch day or should we trade in the day before. So far employees have no word on them doing so but Radio Shack is notorious for not keeping them in the loop when it comes to important information like this.
