A bit pointless given that no software utilises the extra cores yet. But nice to know, I guess.
Mac OS X distributes threads and processes across cores/CPUs to optimize performance already. (Subject to some limitations, as noted already.)
Many Mac programs which can benifit from mutiple threads already use this, and will automatically get boosts from 8 cores depending on the amount of cocurrency they support.
On the other hand, not everything is suitable for cocurrent execution. Photoshop editing an image would love to have a core per pixel. BBEdit couldn't care less, most likely. It all depends on what you are doing.
Plenty of Mac software would use the extra cores, if they were avalible.
(Note: I keep specifying 'Mac' here. There is a reason. Windows isn't as good at multithreading/processing yet...)

Aren't you tired of companies trying to have it their way? Here's what we, as consumers, should do, if that stupid policy happened:
We should create a website, where iPod buyers could subscribe by providing a proof of their iPod purchase. The website would then declare that until Universal pays back what they have taken from every member, those members will steal Universal's music instead of buying it off of the iTS. That's what the tax is there for, right?
Sweet deal! We now have the moral justification to download all of Universal's music for 1 buck. Bring it on!

Did anyone else think it was odd that many of the features seemed so poorly presented. We didn't actually get to see anything new in Spotlight. And no new features of the actual Dashboard were even discussed.
It just doesn't seem that Leopard is as far along as Tiger was when previewed even though Leopard is suppose to ship in the spring just as Tiger did.
Maybe they moved the spotlight bar to the top left and don't want MS to do the same before the Vista release ;)

Under $4k whatever state of the offerings are. I am not writing about wanting to pay for expensive servers etc. I am only referring to Mac Pro top of the lines. So I am looking foward to the 8 core starter kit this Winter. :D
Mine is not RAM intensive work. I have 6GB of ram now and it is more than enough. I also have several Terabytes of HDs already. 400GB HDs are down to $100 now so Storage is pretty cheap.
Yes, with the possibility of a Mac Pro with 8 core on the horizon, it makes sense to skip the 4 core altogether. Or, start with lower end of 4 cores (say 2GHz) and then, if necessary and possible, upgrade it to 8 cores. I wonder if waiting for 8 cores is going to be a common sentiment. In that case, it would make sense for Apple to offer an upgrade path to it.

1) This is all rumour and speculation...
2) At the price that OEMs charge for memory, less RAM is better. We can fill it with whatever we pick.
I used to side with the people complaining about not having enough standard RAM but not after reading that. You get a gold star.

I think this makes somewhat sense... When i went to best buy on launch day they ran out... and then i went back and they were doing $100 pre-orders to be put on a list (which i never ended up doing)... so what they did is had a ton of people pay a hundred bucks to put on a best buy gift card and then "shorten" the supply so that people would have to be impatient and go buy somewhere else--which forced people to spend that hundred dollars at BB.
Kind of a cheap selfish way to make money. hundreds of pre-orders and then only a few ipad sales...
it still doesn't make sense to not sell what you have in stock though... stupid

I'm sure the GPU will also be bumped, at the very least. The MBP will probably also see some things that the MB has like a user-removable hard drive and magnetic latch. The CPU and GPU alone make it worth getting the new one, IMO.
I agree. The practical differences between the Core Duo and the Core 2 Duo in real world tests are tiny.
But a serious bump to the GPU, HD, and the other enhancements you mention certainly would make the upgrade worthwhile.
I Just Hope Apple Joins The Rest Of The Manufacturers In This Mass Announcement. In this case, I wish they wouldn't "Think Differently".
I hope you are right. I would love to buy a MBP next week.
Expect new Merom-based macs, and a new iPod, on September 18th.
I suspect you are correct, but I hope you are wrong. I'd love to get a new MBP in the next couple of weeks before my next international trip. But to your point, I am not optimistic.

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.

How do you get black aluminum? Or is this just a wish? Cause that'd be pretty ill.
And what is the easy access HD bay?It is speculated by some of us that the next MacBook Pro revision will include a Black Anodized Aluminum case. Here is the MacWorld video showing the MacBook's Easy Access HD Bay (http://www.macworld.com/weblogs/macword/2006/05/macbookvideo/index.php) which many of us here think is a Pro feature Apple must implement in the next revision of the MacBook Pro. :)

I am digging all the other challenges, the go-karts are real cool, but easy. The nascar isn't to bad. Although it took me a couple tries to get gold on the 2nd race. Nurburgring is cool, I know the track so its not to difficult. Then those dang bus's. :rolleyes:
I'm looking forward to the ones after I think nurburgring as I haven't done any after that. I also hope I can roll around the top gear track for fun, maybe I have to level up to a certain level.

The battery recall validator also rejected my battery, which is clearly in the range advertised on the web site. When I called the support lines yesterday, they didn't even try to take the call. Today I got through, and I got told by "Rachel" that there were a small number of batteries in the ranges that were manufactured by someone other than Sony. She couldn't tell me who, and when I asked for further information, she escalated the call.
The next guy, whose name I didn't catch, basically said the same thing. When I explained that I would like something from Apple indicating that the public listing on the recall didn't apply to me, he said that sometime in the future (unstated) this will get updated on the website. Since my primary reason for wanting it is to avoid potential airline troubles, that wasn't too great answer. His next suggestion, to print the validation failure, was funny, but not very practical. I fly about once a week, and I've already seen the dell guys being asked not to work on the plane. I don't want to be in that club, so I was pretty insistent that they write something down.
I asked them to send me something (even by fax) that simply said that my battery was not subject to recall, despite the fact it fell into the consumer product safety commission recalled range and Apple announced range (still up, with no amendment, by at https://support.apple.com/ibook_powerbook/batteryexchange/index.html). He could not.
I next got sent to Kelly, in customer service, whose attitude was about the least customer-service related of any of them. She tried to read out the web site to me, and got very frustrated when I pointed out that it did not say what she wanted it to say. It does not say that there are batteries in the ranges that are fine. It says at least twice that if you have a battery in the range you should send for a replacement and not use it. I pointed out to her that the trouble ticket I'd opened covered the ground nicely, and that all I wanted was a statement of the result: "Apple's support staff has worked with this customer and has established that the battery Serial No. XXXX is not subject to the recall on Sony-produced batteries". Or whatever language they like.
She agreed that this was truth, but said she could not provide any documentation. She also declined to escalate further.
Given that the validator has said no to people who should have gotten yes, relying on it as the last word is a bad idea. Get a real person on the phone. But even then, be prepared for frustration if you would like
anything but an oral assurance that the battery you have is good.

Obviously this IS an issue; just not a very big one. Considering the low quality of the data and the nature if what is stored, it is not well suited for tracking user whereabouts with any level of confidence.
Apple does need to address this, but I don't see any malicious intent. The data serves a valuable function for the user and is not collected by Apple.
