I own a Dell XPS and a MacBook Air, which makes me pretty geeky. Both dual boot with their native OS (XP/Leopard) and Fedora Core. The Air was absurdly priced, and has one great draw-back, it overheats (the fan started to produce noise too after two months, which is annoying).
I was a bit worried about having only one mouse button on the Air but the multitouch pad is really great: One tap is click, double-fingered tap is right click, normal strafe moves the pointer, double-fingered strafe is scroll, both vertical or horizontal.
I thought I would have one button too little, turns out I have one button too much.
