I'm looking for a replacement for the T5010 (old and dying) mounted on my daughter's wheelchair that serves as her voice-output communications device as well as general-purpose PC. None of current offerings have what's needed (Vaio Z Canvas comes closest & I could make it work), so I'm looking for a good, used T902. I'd prefer if it has 16 GB RAM and a 256 GB (or more) SSD. Cosmetic state not very important, but function is. I would like to also have a second unit for software development/maintenance for her system. All leads welcome.
