After a few years, my macbook has basically fallen apart, gotten stains that wont come out from book covers, the top case still cracking even after replacing it several times over. The build quality is pretty irritating. My girlfriends netbook of 2 years although works just fine and is of identical thickness. I would like a sony vaio Z series with it's 13" 1080p screen, dual SSDs and 3 pounds of weight vs. a macbook, but have to use it because of iPhone development.
