There are two hot ultraportable computers on the scene now-a-days: the MacBook Air and the ThinkPad X300. Some clever Lenovo lover created this MacBook Air ad parody which points out the key differences between the Air and the X300: number of ports and an internal DVD drive (only available on some models).
Judging by pure aesthetics alone the Air wins, but ThinkPads are time tested workhorses so I wouldn't count out the X300. Either way, this parody is one of the better ones I've seen.
