The Sony Vaio SZ -- my new computer?

I'm replacing my old IBM T42 with something smaller. Sony's VAIO SZ series is in the lead right now, but I'm a bit concerned about the keyboard quality. Any other experiences? I've heard Sony notebooks don't stand up well over time, but you can purchase an extended warranty with "Accidental Damage from Handling" for $199 for 2 years or $299 for 3 years, which makes me feel more confident.

Other top runners are the Dell Latitude X1 and Lenovo X60, but the screen resolution on both of these is 1024x768. Plus only the X60 offers a Core Duo processor. I'd really like a 12" 1280x1024, but no one makes that. Settling on the VAIO's 1280x800 is as much of a comprimise as I'm willing to make.
