At least five years ago, a friend and I were imagining the computer of the future: some tiny little object that projected the "screen" into mid-air. Well, turns out we were close but had it backwards. Yesterday, I discovered the little gadget that projects the keyboard. ITech makes a 3.5 inch gadget that connects via bluetooth technology to a Blackberry and 9 other product groups. It projects a keyboard onto any flat, opaque surface. Cost seems to be around $170 (apparently there's some fluctuation due to currency changes). Reviews seem to be pretty high marks from those who are using it, though there are some pretty low grades from folks who can't get it set up.
