13" MBP uses SV chips, i.e. standard voltage (35W). Before it used MV (medium voltage, 25W) chips but Sandy Bridge does not offer CPUs like that. LV (25W) and ULV (17W) chips have not been released yet but will be released shortly like the article says.
If the clock speed and other specs are the same, then the performance is the same. ULV and LV chips are only separated by the TDP which causes the ULV to have lower clock speed. Otherwise they are the same chips.
So is that also true for the difference between SV and LV? If that is the case, the Core i7-2649M you cite above (2.3 LV chip) should be faster compared to the 2.3 i5 in the low end Pro 13?
Thanks!

Definitely need 8 cores me.
One for running whatever program I'm working on.
One for running the OS X interface, with Core Image, and bells and whistles and brass knobs and shiny candy.
One for running Azerus or LimeWire or one of these Bittorrent clients that all seem to be in Java on the mac, and all slow my machine to a crawl..
One for running Firefox and rendering these java / flash adverts that seem to slow my machine to a crawl.
One for doing the video rendering that still slows my machine to a crawl for hours and hours.
One for running the Windows XP virtualisation machine in a window on my desktop that seemed to slow my machine to a crawl last time I tried it.

I agree with pretty much everyone else here; this royalty notion won't fly with Apple being (for once) in the dominant market position. If Universal pulls their music/content, it'll all be downloaded illegally, since the Zune isn't about to replace the iPod as the must-have 'cool' item (even if Zune marketplace does offer the Universal catalog). Universal just wants Apple to throw them a bone.

Is having more cores more energy efficient than having one big fat ass 24Ghz processor? Maybe thats a factor in the increasing core count.
Absolutely.
The power consumption of a chip is proportional to the clock speed, multiplied by the voltage squared. So at the same voltage, a hypothetical 24 GHz chip would use eight times as much power as a single 3 GHz chip, and the same as eight 3 GHz chips.
However, with any given technology, you need higher voltage to achieve the higher clock speed. So with the same technology, that 24 GHz chip would need much much higher voltage than the 3 GHz chips and accordingly it would take much more energy than eight 3 GHz chips.
As an example, some iPods have two ARM chips running at half the clock speed and lower power instead of a single ARM chip running at higher speed, in order to safe power.

Totally depends on what tools you are using. Sure, when I'm at home working on a light webapp running nothing but Emacs, Chrome, Postgres, and using, for example, Python as my server-side language, 4GB of RAM is more than enough, hell I could get by with 2GB no problem
You'd need 2 GBs for that ? My Linux server with about 384 MB of RAM runs that web/db environnement without breaking a sweat, with a load average of about 0.1, and that's not even a quarter of what runs off of it.
No, seriously, people overestimate their computing ressource needs these days. Xcode is pretty light, Eclipse ran on computers from 10 years ago, so did Netbeans. Tomcat has been around and hasn't changed much from its 5.0 release, back in the early 2000s.
The MBA is fine for running the tools you describe and would make a fine software development station for the needs you expose, don't ever doubt that.
By "run everything", you can't possibly mean run games at "higher than medium" settings, nor edit lots of HD footage in something like Final Cut Pro. Though that's not what YOU use YOUR MacBook Air for
I'd argue the needs I described are shared by much more people that the needs you claim aren't filled by a MBA. I doubt Final Cut Pro movie editing is anything but a small niche of what computer buyers do with their machines and "higher than medium" settings is not something I use to describe gaming. I value games for their playability, not how they look on my screen. Of course, I come from the era of EGA graphics and Adlib sound systems, when games were about gameplay.
Still, the MBA does fine with iMovie and I can play Civilization IV at full screen on my external monitor of 2048x1156 pixels without breaking a sweat. It is a very capable machine, contrary to what you believe. Use one and see for yourself before you diss the thing. I can understand why you wouldn't be interested in one, I can't however understand the venom you spit at the thing.
please, please, P...L...E...A...S...E - Can we have an integrated Cellular data chip
Get a USB adapter. That way, your 2000$ laptop won't be tied to a single carrier the way Apple does 3G in its devices. I'm fine with my iPhone and tethering, I'd rather Apple sell the MBA on the cheap and leave the 3G option up to the users.
It's not like you can't use a MBA over 3G networks right this day (or any other Mac for that matter).
Wait, so MacBook Air has a TN panel? That makes no sense, the iPad 2 has an IPS panel...
Anyway, I'd like to see backlit keys and an IPS display before I buy a MBA :cool:
Very, very few laptops have IPS displays. The only one that comes to mind is the HP Elitebook with the DreamColor screen option (the standard screen on it is a TN panel).
Apple does not install Flash Player on newer machines, so this is not a problem.
Try youtube.com/html5 (http://www.youtube.com/html5) or ClickToFlash (http://rentzsch.github.com/clicktoflash/) or other HTML5-Safari extensions (http://www.macupdate.com/find/mac/html5%20extension)!
Youtube is not the only source of content out there and until all video provider sites are HTML5, computers without VDA framework support will be slower, run hotter and have lesser battery life than those with VDA support.
And HTML5 won't be on all video sites until you can graft DRM on top of it. Think of the paid-for streaming providers like Hulu.
BTW, my MBA runs Flash without any problems. I don't need Apple to pre-install it for me.
You obviously know nothing about OpenCL (http://en.wikipedia.org/wiki/OpenCL). OpenCL is not hardware dependent. OpenCL programs can run even on old 300 MHz PowerPC processors, if someone writes a OpenCL-compiler for this platform.
And you obvioulsy don't understand what a GPGPU API is for. What good is running code through an API whose purpose is to offload your CPU by using ... your CPU. It makes no sense to emulate OpenCL in software, other than providing OpenCL on computers without a hardware implementation.
In the end, you haven't achieved the purpose of OpenCL, which is to offload the CPU, since you haven't offloaded the CPU at all.
The point is, the Intel 3000 HD on Mac OS X cannot run OpenCL code, so it's up to the CPU to do it.
You failed to even counter my points. Your attempt is only about dismissal, which proves my points are very valid.

Although the only thing that will ultimately matter is what Apple releases on Tuesday, if you want to get an inkling as to why FCP development has been at loggerheads since do yourself a favour and read a couple articles from Philip Hodgett's blog on FCP, QTkit, Cocoa, and it's unfortunate collision with OSX's 64 bit platform development.
http://www.philiphodgetts.com/category/technology/apple-pro-apps/
Which has been in development longer FCP overhaul or iPhone?
AV foundation was overkill for iOS from the outset so that would suggest is was always intended for FCP.
His articles have a funny assumption that the OS team has the most secrecy.
Surely the more valuable projects Like FCP have greater access to information and the greater control over when the broader company gets to see their work. Sure they would have been trumped to iPhone team who would seem to have free reign. The CoreOS team would seem like they are the most open their job is to turn the private API's developed by the product teams into to a public developer platform. A lot of their work is even open source.

Yeah! That's what'll happen!
Or they'll do further research and realize that the implications in this SINGLE ARTICLE might not be 100% true.
To the everyday user this means NOTHING as they have no knowledge of what open truly means, and therefore can't take advantage of it.
To the users who actually have the knowhow to utilize open source operating systems, this might mean a minor hinderance, but not a complete game changer.
And for clarification, the former is the vast majority.
Did no one notice the obvious bias in this article? It's slanted, and the author clearly thinks that Google has been wrong this entire time.
The everyday user has been buying Android phones in large numbers because they're cheap and are available on more carriers. This is not about everyday users, it's about the Fandroids who have been screaming "'Open' good, 'closed' bad!!" at the top of their lungs for the last three years.
I stand by my three groups: 1�indiscriminate Apple-haters (like you), 2�people who just want a team to root for: "Go Android!!" Right or wrong, and 3�the true believers in the open-source religion.
Now as I said before, the only truly "open" phones would be FreeRunners that Stallman assembles in his Mom's basement from components gleaned from dumpsters and hands out for free, so I have no idea what new savior they'll turn to to save them from the tyrant Jobs. Be funny if it was Microsoft!
And no, I see no "bias" in the article�I think you're using the Rupert Murdoch definition: "Facts I don't want anybody to hear."

It would be fantastic for the MacBook to have the Core 2 Duo, (MacBookPro is a given), the fact is, Apple needs to do this update to stay in the same ballpark as the pc notebook makers.
Now if they could just give the MacBook a real graphics card, I'd be a taker.

Hey Guys.
When do you think they'll update their website with the new "Mac Pro's"?
Regards,

Assuming they're released, they'd probably bring the Apple Store back online around 2:00pm.
(They traditionally take it down during a keynote...)

I think the improvements to OSX are all well and good, I do think Time Machine will be valued in my home, but it is hard to get excited because 10.4 still seems so new to me. I'm sure I don't even know a lot of the cool things it does.
I was hoping for more in the way of hardware. The MacPro seem fine, even though no new case. WHat is he deal with no new displays, but they did drop the prices a little. I think the iPod is long overdue at this point for a makeover. I guess I'm just a victim of my own unfulfilled expectations.

Sued for breaking what law?
Being sued and breaking the law are two different things. I can sue you for killing the tree between our yards. You didnt break any law, but I can still sue.
I kinda see where he is a bit right. If I turn off or say no to allowing the apps to use my location this might suggest to the user that it is not tracking and storing this data. I do not think that it is a stretch to make that connection.
I do agree this is way out of hand though.
