Kichigai Mentat asks: "When I was a student in High School, I was quite disorganized. I found that a good organizer helped me out, and eventually got myself a reliable Palm m105. As I'm about to go into college, I'm considering picking up a new machine to replace my nearly-dead PDA. However, the selection seems to be either Palm OS, which I find rather limiting in terms of what you can and cannot do on the system (I LIKE being able to organize things into sub-folders), or Window Mobile, which isn't Linux or Mac OS X friendly. What sort of third-party options are available that work with existing PIM apps, will work without Windows, and won't cost an arm and a leg?"
