Hi David, i saw you mentioned the jetBook and i just wanted to touch base on my experience with the jetBook Color. I wrote an entire review on it
here if you're interested in getting the nitty/gritty details.
It large, has auto-page turn functions, audiobook capabilities, languauge learning programs - from what i've seen don't require you to touch the screen at all.
It's also color which is a plus, and not backlit (which makes it a good choice for your eyes).
Just throwing it out there as something to consider.
