I'm mostly happy with my Thinkpad Z61m. It's a 15" widescreen machine that's fairly heavy. Its replacement, the much lighter T61 widescreen should be appropriate. It's much more configurable than the MBP; base configurations are much less expensive, and comparable configurations are a bit less.

I think Thinkpad quality peaked around the 600-series of the late '90s (mmm... carbon fiber) and has been dropping ever since. The Lenovo takeover hasn't helped, but IBM was so far ahead of everybody but Apple that I don't think anybody has caught up yet.
