I love the "T" shaped design. I've had experience with both the "T" and "L" shaped power adapters and found that the "L" shaped version held onto the computer a little too well. It didn't allow for a clean break away every time (by clean, I mean the computer not moving at all). I've never had a problem with the "T" shaped version. Sure, it doesn't look as pretty, but I'd rather have a pretty laptop than one that got pulled off my lap and was damaged in the process (angle of your legs, surface the computer is resting on, humidity levels, etc may be a factor in this scenario).
