I am interested in a wired (NOT wireless) keyboard for a Treo 700p. Does such a thing exist? In particular, I would like a keyboard that draws its power from the Treo via the wired connector. I don't want yet another device that needs batteries, or a special recharging unit, etc. I won't use the keyboard often, but when I use it I don't want to have to worry about dead batteries.

Thanks!
