That's quite relative... I haven't used paper in school for a while, other than to print something out
I use the computer extensive. I've also taken my 8890 on a two day car trip from Jersey down to Florida, and back. Quite useful with the correct map software. It's warm, yes, and a bit louder than most laptop, but you still can't hear it from more than 3 feet away. Besides, its winter here, people huddle around it and enjoy the heat
Weight is not an issue, esp if you have a bag. Battery can't be dismissed, it lasted 2:45 the last time I tested it with just word processing, probably around 3 hours if I conserved. It's a wonderful machine!
