So I have been running Ubuntu on a few older machines and I really like it (10.4 and 11.4 both) and the concept of Open Source (huge Moodle fan). So I was looking at system76 and Zareason, but frankly my wife has an MacBook Air and I love how light and portable it is (while still having some decent power). So I am wondering, do folks have any recommendations for a light (4ish lb or less laptop) thin (1"ish) laptopn that has a decent CPU?
Considering a MacBookAir so obviously I am prepared to pay a bit extra for thin and light. Thanks for any info, opinions, and experience
