but is still more productive because it handles more calculations per clock cycle
I'm no processor geek. I have a basic understanding of the terminology and how things work so correct me if I'm wrong, but wasn't this one of the advantages that the PPC had over Intel chips? Does this mean Intel is moving toward shorter pipes? Are we talking more instructions per clock cycle or what? What does "calculations" mean in this context?
With most processors, especially the Intel/AMD processors, "instructions per cycle" is not a useful number. These processors have both simple instructions (add register number 3 to register number 6) and complex instructions (add register number 3 to the number whose address is in register number 6). A PowerPC has the simple instructions, but not the complex ones. Instead it would need three instructions "load the number whose address is in register number 6, and move it to register 7", "add register 3 to register 7", "store register 7 to the location whose address is in register 6". But the Intel processor doesn't magically do three times as much work. Instead, it splits the complex instruction into three so-called "macro-ops", and does exactly the same work. So in this case, the PowerPC would execute three times as many instructions per cycle (3 instead of 1), but because it doesn't do more actual work, that is pointless. Instead you would count the number of operations, and they are more or less the same.
Intel is indeed moving towards shorter pipelines. They have done that already with the Core Duo chips. Longer pipelines have the advantage that each pipeline step is a bit faster, so you can get higher clockspeed. Shorter pipelines have the advantage that they take much less energy (very important; at some point your chips just melt), they are much faster handling branches, and they are just much much easier to design. Pentium 4 needed absolutely heroic efforts to produce it, and would have needed twice the heroics to improve it. Instead, the Core Duo has a much simpler design, that is just as powerful, and because it was so simple, Core 2 Duo could improve it.
And Core 2 Duo can now execute up to four "micro-ops" per cycle, same as the G5, compared to three for Core Duo, Pentium 4 and G4. It also has some clever features that reduce the number of micro-ops needed up to 10 percent, and some other improvements.

Blackberry playbook = The IPad 2 killer - you heard it here first.
Look at the specs, their greater or equal to the iPad 2 with the exception of battery life.
I'd agree with you, but the Playbook is showing up Sunday for a party on Saturday. It had a chance, but I think the late release killed it.

Man, I don't know why people keep saying this. On OS X, *all software utilizes the extra cores*. The only way it wouldn't is if you have less than 8 processes running, which I guarantee you that you don't. (System alone requires 20-30 processes to run.)
Granted, 8 cores won't make Mail open up faster, but there are still plenty of ways to use those cores, and that's only going to increase as apps are re-written to be more heavily multi-threaded.
NOT TRUE....The Quad core G5 people are in an uproar because Logic Pro only uses 2 cores on the G5....they updated Logic Pro so it uses 4 cores, but the G5 Quad still only uses 2 cores....there are also photoshop actions that are NOT multi core aware so will only run on one core.....Hopefully 10.5 will make all this irrelevant.

While Clovertown and Kenstfield ar interesting as probably going to be the first consumer quad core CPUs, they are currently much like Intels initial stabs at Dual Core, which were largely two Pentium chips jammed together. What will be interesting to see is the second generation Intel quad cores and (probably) first generation AMD quad core CPUs, which should be to Kenstfield and Clovertown as the Core Duo family is to the dual core Pentium 4s, though maybe not quite the same performance jump.

I find your statement back to him a bit hypocritical and quite judgmental. Why are his panties in a twist but not yours?
Your initial reply to him was harsh to begin with and he replied logically. Agree to disagree. Leave it at that.

APPLE I NEED A NEW MACBOOK PRO. I NEED FIREWIRE 800, I NEED A DL SuperDrive, i'd like MEMROM. If you had to releace a half-assed Prosumer laptop in the first place to start your transition for the love of god PLEASE update it now. Its been a LONG time since we've seen any updates. Apple is now competeing in INTEL land, were they need to keep their laptops current. Releace the laptops (notebooks in your case as you like to call them) i'll place the order and wait for them to ship. PLEASE.!

Eh what choices do you have if Apple doesn't wish to play by your needs... buy from another vendor? Let the "free market" decide? Oh wait, I forgot, for Macs there is no free market, it is basically a monopoly.

Funny also that we heard a DAMN THING from the media regarding the fact that ONLY CONGRESS can declare war.
It's funny too how a GOP controlled House of Representatives found it so important to spend time debating whether to defund NPR, but couldn't find the time to debate the value of using the military in Libya.
Though, for what it's worth, I'd much rather we returned to the constitutional practice of getting approval from congress before committing ourselves to military intervention.

I have a 13" ultimate of the current generation. The limiting factor for me is the graphics, not the processor. so going to sandy bridge with the intel 3000 would be a less appealing machine for my uses than the current model. It's really too bad the sandy bridge macs are tied to those garbage integrated graphics.
Since you have no clue how the sandy bridge airs will perform, I'll take your statement as FUD.

The biggest advantage always given for Android over iOS is that it's "open source." Well, clearly that's not the case anymore. So, I can't think of any other reason to use Android over iOS, or even Windows 7. It looks like junk, and it's just a cheap ripoff of iOS.

Okay, Knight, you're right. Even the Verizon Galaxy S has more buttons and a patterned back, with a rectangular lens and flash area. Not to mention a WVGA AMOLED screen.
But it does have a chrome trim ring and the back is curved for comfort!
Yeah, Apple is reaching a bit here.

If one were to buy a mac pro now, is the processor upgradeable to Clovertown in the future, or is that not really worth it even if it is, because you would need a faster FSB, meaning a new logic board, to take advantage of its power?
i think it is socket 775 or what ever. and if clovertown is pin compatable it will work. i think the processor will have to deal with the slower bus. as long as it is pin compatible.

When I first saw this feature I thought great. I do regular back ups, but some of my AW docs keep corrupting (probably something to do with keep duplicating the same old document and modifying rather than starting anew). Time Machine will help me no end. I was also thrilled that windows had nothing like this........ until I read through these posts.
Then it seemed very similar to what was coming in Vista and I felt a bit dissapointed that Apple had made such a point about M$ copying them, but seemed to do the same themselves with Time Machine.
However on closer examination this is not the case and my confidence in Apple's innovative skills is restored.
Firstly, there has always been back up and restore apps, so if you want to take this copying thing to a ridiculous level, of course you can do. Copying in my book is when an app does and looks the same (just like the screenshots in the presentation, safari RSS/IE7 RSS, ical/M$ calender etc). It appears to me Time Machine does much more than anything before it and has it's own unique UI to boot.
Secondly, I would imagine work on Time machine started long before a beta of Vista was released, even if the two utilities were more or less identical it would be coincidence not copying.
Thirdly, it seems quite clear that Vista's restore (whatever it's called) will not do what Time machine will do. Ultimately you may well be able to restore any deleted or modified file in Vista, but it doesn't appear to occur with the same ease or functionality.
If I create a file, modify it and move it several times, rename it, convert it, modify it some more, move it several times and finally delete it, I rather suspect it would be an absolute nightmare to recover in Vista, whereas it seems that Time Machine would have little problem.
I don't see how it is possible in Vista to perform the recovery with either the same simplicity or pizzaz as Time Machine. Perhaps if M$ had not abandoned their intended file system for Vista it might have been possible, but as it is I doubt it.
Finally it does not appear that Vista has the option to restore within a database application (i.e. iphoto, mail, address book), no doubt if you understand how a particular database works, the possibility exists to restore a particular photo, but let's not pretend it will be easy or anywhere near the experience of time machine.
And finally, finally, although I agree the UI may appear a little childish, this is exactly the sort of thing that makes it so easy to use.

I totally forgot about that! What a joke. Apple has become the king of hypocrites. And they copied the Apple logo from the Beatle's Apple Records.

Even if that were true, so what? Apple Records was not a competitor of Apple Computer. Trademark law allows multiple companies to have the same trademark so long as they don't sell the same type of products in the same location. This is why you can have a 100 companies like "AAA Locksmith, AAA Laundry," etc. Or you can have "Hollywood Video" in Michigan being totally different than "Hollywood Video" everywhere else [interesting story that. I may have the state wrong. Federal registration grants national scope, but pre-existing competition is a problem]
Only truly "famous" marks (e.g. Coke, McDonalds, etc.) which can be "diluted" by use with other types of products are protected against this sort of thing.

Been on Lion for the past month and I can't see myself going back to Snow Leopard.
This WILL be a landmark release for Apple and huge step forward in usability. It just ties everything together: one simple, elegant, functional, totally scalable OS. Apple will have achieved in no time at all what the competition is just beginning to attempt (and fail at constantly.)
Wirelessly posted (Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_1 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8G4 Safari/6533.18.5)
This might explain the shambles that is 10.6.7.
Last release before Lion - semi-brick your machine to force an upgrade.
iOS 4.3, last release before iPhone 5 - murder your battery to force an upgrade.
You've guessed it, I'm not very happy with Apple at the moment. So which is it; underhand tactics, sloppy Q&A or declining standards?
I think it's artificial belly-aching on MacRumors in order to get attention.
Am I getting warmer?

I don't understand - you can't "add" 3GS, because 3GS is not a data network. 2G and 3G is� the S in the iPhone 3Gs simply stood for "speed", because it was faster than the iPhone 3G.
"the 3GS also adds support for 7.2 Mbit/s HSDPA allowing faster downlink speeds"
http://en.wikipedia.org/wiki/IPhone_3GS
Technically he's right.

I am fairly confident that rather than pointing to a conspiracy, this simply shows that when scanned, the operator had enabled some sort of "auto-text" option that attempted to read and convert then embed the raw text info in the PDF, as to make the text "selectable" in preview programs.
It only worked on certain text, as is par for the course.

Apple has sold what, 70m (ish) iPods since launch. What's it running at now about 10 a year? That's about $10m in revenue Universal could get a year.
If they walk they are losing a share in over 1bn songs translating to a whatever share they can get (say 10%), which would translate to $65m in revenue (2/3 of 10% of 1bn)**
Universal would be killing the golden goose if they were to try to force Apples hand, and Apple said "feck off then and take yer shite music with ye"
Apple on the other hand only stand to lose maybe $4-5m.
** the assumptions may be way off, but it's illustrative anyway. Feel free to correct the numbers

Speaking of wish expectations Multimedia;
I know you're hangin' out for Santa Rosa. The article mentions that it's expected in early 2007. Do you think that would be the date for official announcement of production-standard architecture, or actual availability announcement?
Seems very early to be shipping...
I could go out in September and get a Merom notebook, but I don't mind waiting 6 months for Santa Rosa to hit the street.
