I can't stand Laptops... they're just so tiny. Teeny weeny things that I can crush with two fingers. The battery life tends to be pretty horrible unless you do all that energy efficient stuff like run at low brightness, don't listen to music, don't play any games, don't look at the screen funny, don't cross the streams, don't eat your hamster... etc etc.
Desktop born and raised, baby. Just because I can't carry it around doesn't make it any less useful, especially for using graphics design software that requires rendering, gaming, movies... and such. I will admit however that I use a lappy for writing, mostly because the best ideas always come when you least expect it.
So what I'm saying basically is... laptop good for writing. Me john, big tree?
