You sound like a good customer for the N800. It's what you want, it seems to me.

A lot of people are buying 770s these days, despite the N800. I wouldn't do it myself, but they seem to be having fun. The same thing would happen to those of us with N800s if an N900 came out tomorrow.

Do you use any old calculators that aren't state of the art? A lot of people do. They might be happier if they had a more recent calculator, but the old one does the job.

The N800 is cool and light and will do more stuff than you probably realize now. You may as well get one.
