My wife recently decided to make the switch to a MacBook and she got the Unibody MacBook....and it is awesome! Although I will stick with my Blackbook as it's a perfectly good machine, I am really impressed with the Unibody. I didn't care for how they looked online, but in person it has blown me away. It truly feels like a solid machine and the differences in sturdiness between hers and mine is quite noticeable. The trackpad is easier to work with than I thought it would be. This is the first time I've ever wanted to upgrade, just to upgrade. I won't do it as the practical side of me will win the battle, but I just had to say Apple has done an excellent job with their Unibodys.
