It's hard to type documents and long forum posts with a PDA... ^_^;
Weight and size is important to me, though, probably because I'm a girl-on-the-go. I'm always running all over the city and sometimes airport-hopping. I've never liked hefting massive bags, and even as a student I opted to leave my textbooks home in favor of thinner photocopies of the day's text. My laptops have never exceeded 1.3kg and are always the ultraportable light (Thinkpad X40, now X60) and they fit into my handbags with the cords and all. It can't imagine lugging around anything heavier. Q_Q
Not all those who wander are lost.
