PalmOS also has the problem that its single-tasking programs can write all over the internal RAM, with fatal resets as the nicest possible result (and white screen of death+losing everything installed is another one). I like PalmOS a lot, but there is simply no memory protection. If you use it a lot it will crash, and in a much more problematic way than if an application on the N800 fails, where it doesn't affect anything else and you don't need to reboot. I have a Linux-based Zaurus PDA too, and in the years I've owned it it hasn't had a single reset or crash or failure or anything _ever_. Not one. The uptime is astronomical (as it's Linux you can actually get a shell and enter the 'uptime' command, just as with the N800). This level of stability is also possible to achieve on the N800, although we're not quite there yet. As for PalmOS, if it works out I guess the Access version with PalmOS as a GUI on top of Linux is the best you could hope for, stability wise. I'm keeping an eye on that development.
