I use this also, and it has been a lifesaver for me. I have used the
HeadMaster since my accident 7 years ago, and am now a senior in high
school. I do all my homework with it. I type using an on-screen keyboard
program. I use Doors II from Madenta (www.madenta.com) on the Macintosh
and WiVik from Prentke Romich on Windows. The device is great but I have a
few complaints:
1). The switches on the HM break way too often. It's a poor design.
2). Prentke and Madenta don't have the greatest service.
3). These products are very expensive.
