I am wanting an older PDA that runs on aaa batteries, I am not interested in any lion battery types. The Palm m125 can take a sd card up 1 GB but has a 160 x 160 screen res. The Sony SL10 has a 320 x 320 screen but is limited to a 128 MB sd card. my vision is not very good anymore although I do wear glasses. maybe it will help if I tell you what I want it for, a portable electronic bible, but I want a software bible that I can use a search function as I do with E-sword and others. I am not looking for just a reader. these are the two choices I seem to have right now unless anyone knows of some others? the aaa battery is what I want as a feature, I can carry two extra batteries or more all day long, so a quick swap if needed is what I want. I have already downloaded some palm Bible software.
