Ask HN: Which Non-Macbook notebook would you recommend?

Hey All,

Need recommendations for a Non-Macbook notebook with these 2 chief requirements:

1. Longest battery uptime. 2. Excellent build quality.

Appreciate all the help I can get.

PS: I've got nothing against the Macbooks, its just that I live in LinuxLand and I'm in love with Ubuntu 10.04.
