I'd have to cosign a previous post: Dell Vostro or Thinkpad T61. Do NOT get a Vaio. I've had a FZ-190 for about 4 months now. I got it for the exact reason he suggested, I really liked the MBP but knew I wasn't going to be using OSX as my primary OS (ubuntu) and the FZ matches up perfectly in terms of size/features. Problem is, the Linux drivers for this thing absoutely blow. No function keys, no video out, no webcam.

Another thought: they're a little harder to get, but Asus makes some great models.
