https://alphasmart.com. I've heard rumors some developers from the Alphasmart of old are part of the team. Oh, please let it be true. If not, my Macbook isn't half bad. But portable writing at a picnic table in the sun - just like in the old Alphasmart days - that would be cool. 700 hours run-time on three AA batteries, that was cool, too. I always replaced the batteries once a year. Generally they were only half gone.
