I'm totally illiterate in PDA. I wonder if some one can shed some light on which PDA is more practical. There seems to be two broad types: pocket vs palm. What are their differences, anyway? I'm more concerned with the following aspects: medical resources available (especially the free ones, like dictionary, bugs & drugs, anatomy, diseases, etc.) can read word, excel, powerpoint, pdf file transfer to PC connect to internet long battery life color vs B&W and ??? mp3, camera, games.....these are junks for me.
