Sounds like a great idea!

What are the possible technologies that Art can comfortably use?

There are tablets that are touch screens, there are all-in-one computers, and there are various small laptop types (netbooks, etc.)

How is Art's dexterity as far as typing or touching? You've used Dragon, Kat - what all devices can it be installed on? The questions that need answering are: is it now easier for him to sit at a table and type or touch a screen, and/or would it be easier to have a small device on his lap or lower work surface than a desk?
