Ha! The linux pda, I have one of those in a box somewhere. When I got it, I was working a mindless corporate job, and planned to use it do some development during my plentiful free time (at work). That never worked out, needless to say. The most dev I did o it was a j2me text editor that read and stored files to the device. Seems like I installed openzaurus on it back then.
Feel free to contact me if you're interested in selling it :D (details are in profile)
