I have a Treo 650 and am enjoying reading books on it. My wife has noticed and would like a device to read books but does not want a heavy phone like the Treo. What relatively inexpensive device can I get to allow her to read books, preferably a palm, that will also allow her to keep her schedule? Palm Tungsten of some sort? Thx for any thoughts. I don't know a thing about the current line of Palm PDA's.
