The only thing about these that I am interested about is the new manufacturing process. I'm curious to see if this really improves build quality and durability, which has been one of my major issues with Apple's laptops in the past (and why I have and continue to buy Thinkpads until they start getting it wrong).
Other than that, I don't care about the glass trackpad. I used to hate the trackpoint like most people until I started using them on Thinkpads and now I'm a trackpoint convert.
I'm really shocked to see the elimination of Firewire since Apple has so long focused on media superiority (as a perception, even if the reality is there's no difference). Firewire is a preferred interface for external drives and many video cameras use it (even my still camera does).
I am also not a fan of the new display. I didn't like the black bezel & glossy display on the iMac and I sure don't like it here. Job's rationalization that you can always re-angle your laptop and turn up the brightness is true... sometimes. You can't always turn or tilt your laptop for less reflection and boosting brightness, even with LED backlights, is still a bit silly on a battery operated device.
I am however glad to see that they incorporated the switchable graphics. My T400 has this and switching to integrated makes a significant improvement in battery life. Right now it looks like I could get 5 hours on my fairly loaded T400 which has a 2.53Ghz T9400 processor (not the most efficient one available, it's in the more performance oriented line with more cache) using a 6 cell battery. When the optical drive shuts off and the wireless is off, I can get closer to 7 hours.
