I see what you're getting at, Bob. I think of my Parents & in-laws, and a number of my co-workers for that matter, who can more or less use a computer, but get stumped really quick if they wander outside of the basics like word-processing & e-mail. They'd be
totally adrift with a smartphone, to the point of having trouble using the phone part in the midst of all that 'technical' stuff.
Something like the Foleo very well might just bring, say, a Trēo into the realm of graspable to them. I guess it's no wonder that I don't see a use to me personally for products that aren't aimed at me. As an apartment dweller, I don't have much current use for a lawn-mower either, but that doesn't mean that mowers are inherently useless to everyone.
