I recently had the opportunity to see the Fly Pentop computer from LeapFrog demonstrated at a conference. They were available on ebay so I picked one up and can't wait to test drive it myself. It appears to have some educational applications beyond what the company touts. The scheduler function may be helpful for kids who need auditory organizational cues to stay on task or as a reminder. The writing function may help students with letter formation.
I'll report back after I receive it and test it out with my two teenagers.
