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.

Meanwhile, Apple is drowning in orders and battling light leaks (http://www.electronista.com/articles/11/03/22/buyers.complain.of.multiple.faulty.replacements/) in displays. If the quality cannot be improved expeditiously, would-be customers may investigate the competition. :(
Yeah, with problems like that they are destined to fail. :rolleyes:

Since the WWDC is focused on developers, wouldn't it make the most sense for Apple to do all of the chip transition announcements plus the Leopard preview at WWDC and wait until MW SanFran or hold a special event for the video iPod/iTunes movie announcements? After all, developers want to know what to expect in the forthcoming OS and what the processing abilities for the full range of hardware will be so they can devise applications to fully exploit the specs on the OS and the various hardware configs. iPod and iTunes announcements may be neat, but they would seem to be less relevant to the WWDC audience.

I guess the republicans can maybe now look at the issues.
I am glad that Obama put out the papers to shut the conspiracy theorists up.
Putting the papers out has made all the people who spewed this crap look like total and complete fools; and exposed their racism for all to see and mock. :D
For all the GOPers who wouldn't tell the racist fools in your own party to drop it, you are complicit in this farce. John Boehner, I'm talking to you! Yes, it was your job. (http://www.mediaite.com/tv/speaker-boehner-its-not-my-job-to-tell-americans-that-obama-is-not-a-muslim/)

Oh yeah... and here's a fun little nugget for those who like to tout Obama's coalition:
Here's a little fun little nugget for those who say "Obama's just Bush all over again."
UN Resolution 1441 (2002) was drafted by the US and UK, and presented at the UN by Bush.
UN Resolution 1973 (2011) was drafted by France, Lebanon, and the UK, and not presented by the US.
Like you, I would rather us not be involved at all - but we hardly have quite the same hand in this latest business as we did when we went WMD-hunting...

It would be nice if 10.5 would allow a more 'blind' method to utilize these cores, versus having programmers specificly program for multi-core. Now that would be extremely helpful and allow a more simultanous workflow.
How much more 'blind' do you want it? All the programmer has to do at this point is use multiple threads. Even if they don't, multiple cores will be automatically used for system and other processes.
Splitting one thread so that it ran cocurent with itself is a recipie for massive trouble. Mac OS X is about as blind as any system out there for the programmer. There may be some more optimizations that the system could make in it's own handling of multiprocessing, but from a programmer's perspective it doesn't matter how many cores the system has. (Unless you really want it to.)

All of the reviews of the Core 2 Duo say that it crushes AMD in the desktop arena. This is good news
This week, anyhow. This stuff goes back-and-forth like a tennis match.
I don't know if it's a good thing or not, it just is. I prefer AMD on the whole, as I like their design philosophy. But, I'm totally happy with the Intel chip in my MacBook. Whatever works. I find as I get older, the same computers get faster while I just get slower. :D

I think this IS a privacy issue. That data could end up in the wrong hands. Does anyone store a text document on their iPhone with a list of their bank details and passwords? No, because it could end up in the wrong hands. So could this data that's being collected.
This data shouldn't be recorded without permission, no matter what's being done with it.
And the next time somebody calls you, make sure you get their permission to store their phone number. Don't want to record their data without their consent.

And the Apple haters do yet another 180...
1. Macs
1995 to 2007: Don't use a Mac. Noone uses Macs.
2007 to Present: Don't use a Mac. Everyone uses a Mac.
2. Apps
1995 to 2/22/2011: Don't use Apple. There is no software and they can't do anything.
2/22 to Present: Apps? Who needs Apps as long as you have a robust UI?
3. Open
2007 to Today: Apple is a walled garden that only stupid lemmings use.
Today going forward: Controlling the OS is necessary and good for the consumer.
Exactly! I've heard every single one of those arguments, except instead of a lemming ... I'm an iSheep!
And for those of you that add "customizing/theming" as a great feature to Android, please take a look at what your peers are proud of. http://fuglyandroid.tumblr.com/

Isn't it all hormonal mishaps in the womb? Does your God control that? If so, he is predisposing people to sin, and isn't that unfair that not all are exposed to that disposition?
AFAIK, Christians have this idea of "inherited sin". The predisposal to sin doesn't come from God, but from Adam.

Reading most of the posts, especially the negative / critical ones, I'm relieved that you guys don't work for Apple!
IMO, Lion will "merge"/"blend" some of the IOS look and feel. It will be a great selling point for those who own iPhones and iPads, but have not taken the Mac plunge....familiarity will be a huge selling point.
Don't like Launchpad? Don't use it. Use the dock or finder. I don't use spaces, but know many who swear by it. To each, his own.
I welcome the next version of Mac OS X, but I do not expect something so radically different that I'm setting myself up for disappointment.
Cheers....

This is just a preview of the future, Android based tablets will clean the iPads clock. Apple made the so-called iPad 2 as a 1.5. Low res camera, not enough RAM, and low res screen. It's going to be a verrrry long 2012 for Apple. Sure it's selling like hot cakes now, but when buyers see tablets that they don't have to stand inline for, that have better equipment and are cheaper ... Apples house of cards will come crashing down around them.
The only strength that Apple has is the app ecosystem; which is why they are going after Amazon for spiting on the sidewalk. They know the world of hurt coming their way.
Phew, I was beginning to get worried that you hadn't chimed in with your "opinion" yet. Given that everything you've said in the last six months or so has been absolutely wrong, I'll consider your post a guarantee of the iPad's success. Buy buy buy! ;-)

I have a few quick questions for anybody that works at Radio Shack:
I plan on going into a Radio Shack store on Tuesday to look into Appraising my iPhone. Do I need the Original Box? I have the Accessories and the books that came with my iPhone, but don't have the box.
Also can I just get an Appraisal without having to agree to it? and
Does my phone have to be resorted to factory setting and my info wiped off if I'm just going in for an Appraisal?
If I decide to go along with the Appraisal and Pre Order an iPhone 4 does the store take my iPhone that day? Or do I keep it until I get the iPhone 4?
I was also wondering if it makes any difference in the appraisal if the phone is a Refurbished or not? My Girlfriends is a Refurbished one.
Sorry for all the questions.
Thanks!!!

I think Apple might have much better luck showing that the Galaxy phone shape greatly resembles the 3GS.
Depends on which model. The AT&T/Rogers Galaxy S Captivate hardly ressembles the iPhone :

I'm also hard-pressed to see how the Nexus S comes even close :
