Picsel Browser for Zaurus - search the OESF forums for various descriptions about this amazing piece of software that lets you view MS word files, PDF's, etc. For example:
I used this without any problems on my SL-C3000 with the Sharp ROM. It *may* work on other Sharp-based ROMS, but I make *no* guarantees of that. But I will guarantee that it works with the Sharp.
I'm selling it for $100 on the included 256MB SD card.
Any questions? Please ask!
