They've all got High-End Processors (fastest Sandy Bridge Mobile Duo and Quad-Cores without going into the Extreme Series) so they've all got Hyperthreading and Turbo Boost, mostly 2.0 which can bring most CPUs to around 3.0 GHz. Beats the Core 2 Duos by a long mile, even if the base GHz is lower.
They should have really bumped the 13" resolution too. The MBA can do 14xx native, why can't the MBP.
For the SB Kernels: Just need someone that's buying one of the new MBPs to upload them to someone, from there, hey, its the Internet. They'll spread like Wildfire
Just something minor that I've never quite understood: They have the same screen size models, only difference really is the CPU, sometimes the GPU. Why do they not just have 1 selection? I mean they've got 13" - 13" | 15" - 15" | 17" Why not just one "Select" button per-screen size and let people configure Processor etc from there? /Confused.
Like right now, the 2 13"s, the only difference is the Processor. They could have it all under one Menu and let people choose whichever Processor. Like this we need to fish out the changes from the Menu. Confusing. Anyway.
P.S. 13" does have SSD options, although from what I hear Apple SSDs performance is reduced over time (plus they cost so much), would personally recommend an OWC SSD. Better speeds too.
