I just purchased a little HP 11" Stream, and the build quality is pretty good - I was pleasantly surprised, especially for a $199 laptop that includes $125 in free software coupons. (Pro-tip: if you need a Windows laptop, but it directly from Microsoft so you don't get any crap-ware loaded on it.)

That said, I am kind of looking forward to my (about) 4 year old MacBook Air eventually dying and then I will buy the new model that was announced today :-) MacBooks are beautiful.
