We really should be hoping that Thunderbolt succeeds and USB 3 fails. USB has always been a hack for lowest common denominator PCs and PC manufacturers who were not interested in investing in quality external communication.
USB is a poorly designed protocol, and rather than fix it, they have just extended it with USB3, and pretend like it is faster.
In real world use, USB3 is more like 2.5Gbps-- one way.
In real world use, Thunderbolt is 20Gbps-- both directions. (two 10Gbps channels)
This means Thunderbolt is effectively 20 times faster than USB3 -- if you maxed it out. Right now the two are competitive only because we don't have external devices capable of maxing out the bandwidth... but eventually we will.
I'll have to seriously considering delaying getting a new iMac until 2012 now. I don't want to be caught having to buy more expensive Thunderbolt external drives. Thunderbolt is great only if the drives are no more expensive than USB 3.0 drives.
What will be cheaper is whatever is the more popular. Thus we want Intel to delay support for USB3 and give thunderbolt time to be adopted widely. We really need to avoid another Firewire situation here, lest the entire world be held back by a crappy, second rate technology that is ubiquitous.
Look at the price difference of a USB 2 hard drive vs. Firewire- that is purely due to the USB market being bigger, it has no technological reason.
Think about the millions of people copying large files onto 1 or 2TB USB drives and how long they have to wait.... with no advantages of USB over Firewire.
USB2 is not even as fast as Firewire 400, let alone Firewire 800.
Drat, I just bought a MBP, first laptop upgrade in 4 years :( Hopefully we get a Thunderbolt-to-USB3 connector.
Those have been announced already at this weeks NAB. Apple will likely include USB3 in their laptops, though.

So, Leopard has some features that haven't been revealed yet.
Could one of them possibly be the rumor of having a Bit Torrent client built into the OS.....

Which would make the possibility of downloading higher quality videos plausible....

I'm amazed that no-one is seeing the very dangerous path we could be heading down here. Will people only see it when it's too late?
Are we looking into the jaws of the future where you pay, but never OWN anything? Music, Movies, Apps.
You pay to have the right to listen/watch/use the data.
The data is never downloaded to your device to do as you wish, it's always held by the owners. or distributors.
I can see this coming like a flashing red warning sign.
what are you going to do with your downloaded song? if you still use cd's, you're an old timer when it comes to technology. My wife and i both listen to pandora/itunes music in the car and hooked up wirelessly throughout the house. Boom, all the music in the cloud service could be right there right now. Instead of having to go to my computer, sync what music i want so i can load up my phone with music i want for my trip.
Times are changing. Once this cloud service is the standard, you won't have to have multiple hard drives with your data or music/photos. Go look at dropbox and how popular that is. There is no need for users to have mass amaount of storage when you can access it in the cloud.

Seriously, I am suprised these chips are pin-compatible with the Conroe, which is pin compatible with some P4s. Seems like the next REAL boost in intel performance will be the summer of when the next-gen chipsets and such are released. (as previously posted)

I wondering how many people are now going to put off buying a Mac Pro and wait for a faster Kentsfield :confused:
The Mac Pros a fast as it is now, Kentsfield would smash the previous benchmarks but a fair margin.

Kernel
A privilege checking issue existed in the i386_set_ldt system call's handling of call gates. A local user may be able to execute arbitrary code with system privileges. This issue is addressed by disallowing creation of call gate entries via i386_set_ldt().
Generating a successful malware from that list of vulnerabilities has two requirements:
1) A remote arbitrary code execution vulnerability has to be linked to a local privilege escalation vulnerability.
2) Those vulnerabilities that can be linked together must both be exploitable. Not all vulnerabilities are exploitable.
The only local privilege escalation vulnerability in that update is shown above. To be linked to a remote vulnerability to create a successful malware requires the following:
1) The call function must be used by a process that also has an remote vulnerability so that the vulns can be linked together to install a payload, such as rootkit. It is likely that not all processes will use that call function. Also, that call function is for 32-bit processes and most client side software in Mac OS X that may contain a remote exploit are 64-bit processes.
2) The two vulnerabilities have to be reliably exploitable once linked together as well as being reliably exploitable independently so that they can actually be linked together. Again, not all vulnerabilities are exploitable.
Linking together remote and local exploits is more difficult in Mac OS X than Windows. This is because Windows has far more local privilege escalation exploits than Mac OS X. Another factor is that the different levels of Windows are less insulated from each other than the different levels of Mac OS X. A common method to achieve privilege escalation in Windows is by manipulating registry values.

Kind of a huge gap, don'cha think? For an extra $100 I can nearly TRIPLE the capacity? Why would I even consider a 30 GB model?
Actually $100 is a lot of money. Especially if you don't need the capacity.
The main thing for me though is size. The difference in width is only a few tenths of an inch but the 30G is definitely slim and it feels pretty light in the hand. I'm not sure that's really the case with the 60G/80G. The iPod is primarily a portable device afterall.

The fact that the new iMacs can't address more than 3Gb of memory and are therefore operating on a 32bit logic-board makes me doubtful as to whether or not these systems are really 64-bit capable... It seems like some kind of hybrid 32/64bit system.
Will the C2D iMacs be able to run 64bit code, despite not having the 64bit address space (and being able to access over 4Gb or RAM)?
I would expect so. I would think that userland apps will get a 64bit address space that's just mapped to 32bits in the kernel. But I've been known to be wrong before. :)

My Guess:
Just think if that Data Center Apple bought was acctually a place to store alll the studios movies. Then you pay 9.99 for the rights to what ever movie and it is streamed Slingbox style to your Airport Extreme that has HDMI, Component, Composite etc outlets for your TV. Then you have your movie you bought anytime all the time but never have to take storage of your own, and never have to deal with downloading or anything.
You heard it hear first!
Actually, that idea has been pitched before. ;)
I'm not sure if I would care for that sort of service though. I'm thinking I would most likely just burn off a purchased movie to DVD, as long as it's possible of course.
Having it remotely hosted would be nice if you're going somewhere else to watch the movie, but that's dependant upon the fact that this "somewhere else" would most likely need this device as well.
It's a solid idea, I just don't see Apple doing it.

What it comes down to is Microsoft just wants to leech off of a name Apple has worked hard to build over the past few years. I'm sure if Apple did not popularize and create such huge mindshare with the App Store Microsoft would have probably have gone with something like Microsoft Application Marketplace.

I am so sick of these Greenpeace people -- pushy-shovey types with nothing better to do than harrass people when they're trying to have fun at an Expo. Don't they realize the people they want to convince are huge Apple supporters and enthusiasts -- they don't want to hear some downer telling them negativity about Apple.
Apple might not be at the top of what constitutes eco-friendly for GP, but they're doing ok. In my opinion, when a person buys a computer/ipod/whatever, it's THEIR responsibiity to do something with that's eco-friendly-- if they don't know what that is, then they need to be educated.
Most educated, computer types would be more than happy to do the right thing if they just knew what that was. In fact, the dumb ones would too.

What is NIH syndrome?
NIH = not invented here. apple was notorious for this behavior in the 80s and 90s, much to their detriment, and success.
Just to further clarify -- NIH syndrome is when a company chooses not to use technologies invented by other companies in its own products. They prefer to design and build the entire package themselves, in-house.
I'm not that interested in an iPhone. Apple would need to add some very unique features for me to consider buying one.

The MBP 13" is not quite the bang up job. It got a GPU downgrade and the benchmarks show it. The MBA won't be any different. There's no doubt about it, if you're looking for a GPU upgrade, go look elsewhere.
It's just the reality Intel forced onto us, why does anyone want to live in denial ?
For 99% of the market, the integrated graphics are fine. The majority of consumers don't read tech sites and are happy with the performance. The typical pc buyer doesn't know what a benchmark is. In almost every Apple vs Winodws pc argument on this and every other Mac site, the Mac fans without fail say specs don't matter. If you're a gamer, you'll notice the performance hit. To the million plus people who will buy the next model it won't make any difference.

I just watched the stream. Not before Christmas. Jobs made it pretty clear that these updates and new iPods are the holiday product line up.
That's just sad. Incredibly, incredibly sad.
Guess I'll go hit ebay for a 4th gen 20 gig since the 5th gen offers nothing new (4:3 2 inch screen video playback is not a "feature") and this 'update' offers even less.
I'd be surprised if Apple sells HALF the number of iPods this holiday season vs. last.

As much as I love rumors approximating nearer and nearer some state of acuity, actually seeing the product a day ahead is a tad disspaointing. It reminds me of the late night when Time Canada unveiled the G4 iMac. Well it'll still be fun to watch me Opie tomorrow, especially since she's promoting iPods over the Dell Ditty she did a couple years back.

Maybe because most manufacturers have started selling Core 2 Duo computers but Apple hasn't.
I'm guessing it's because every computer maker has announced the new Core 2 Duo but Apple hasn't.That's why I voted negative.
I guess Apple needs to change their "update tuesdays" to match the competition eh? In other words, update on other days as needed.

They don't want to call their store "MobileApp" because they already have a store. It's called "Marketplace".
They would however like to describe their store that called "Marketplace" by saying that it is a store that sells apps. You know, an app store.

The biggest advantage is that you get quad cores without having to pay for Xeon chipsets and memory.
It's also big for the Windows/Linux side of the world. Much of the software is licensed per socket.
- XP Home - 1 socket
- XP Pro - 2 sockets
- Win2k3 Server - 4 sockets
With a quad core, you can run an 8 CPU XP Pro system without forking over the bucks for Windows Server. Add to that per-socket licensing for many software packages, and it's a huge cost savings.
Careful here - it's almost as good as the current Mac Pro quad configuration. There you have two dies communicating over the FSB and Northbridge...Oh yeah, I forgot about the Windows socket limitations. I know it'll be a great performer but a "better" chip will always come out later. Kentsfield appears to be an Extreme Edition chip until quad core trickles down to more normal desktops. Still, I can see some new Mac Pro running off a single Kentsfield.
