And if no zoom, read http://www.cerience.com/compare/devices/
My wife just got a Palm Tungsten E and she likes it a lot. I would like something like it but I have a concern. I loaded Adobe Reader for Palm and tried to view a map. The map was a full 8 X 11 inch rail map of Tokyo but the map was shown in full page and the lines and text was so small it was worthless. I would us it for vacations to keep maps of hotell locations, rail lines and stations. My question is does other PDA makers' have a version to Adobe Reader that has a magnification or zoom feature?
