Someone is selling a second hand P800. Is it worth paying about half the price of a new 910 for it? More importantly, can it replace my Tungsten E? I use my Tungsten for the standard features (address book, calender, tasks and memos) but also use dtg to read word and excel documents, acrobat reader, avantgo, realone player for MP3. I enjoy the ability to view photos downloaded from my PC and Kinoma for video clips but could live without these. Would the P800 allow me to do the above?
