I still check back every month or two for interest's sake, but I haven't posted in almost two and a half years. I probably haven't touched my Zaurus in just as long.
pdaXrom was the closest I ever got to making it a useful device, but never quite got there (the 6000 seemed to miss out on a lot of the good stuff). Doesn't look like that's going to change any time soon, but I might get it out and play with it again one day. It's amazing to think that it's still quite a powerful device by today's standards even though its four years old!
Welcome back!
Yes, it's amazing how powerful these devices are. Have you thought about selling your 6000 and getting one of the clamshell models? SL-C1000 would be good enough unless you want to install OpenBSD on it, which AFAIK is not possible.
I have an SL-C1000 and it is literally like a miniaturized laptop. I'm running pdaXii13 on it at the moment with Fluxbox, ROX, etc. I can watch movies (mplayer), listen to music (XMMS), write documents and export to different formats including .DOC and .PDF (Abiword), read PDF (xpdf) and CHM (xchm) files, keep an agenda, addresses, passwords (KDE PIM suite,) play arcade games (pdaXmame, although I still haven't figured out how to run them at fullscreen), and about any other thing you can imagine, including browsing the web (Dillo, very fast and acceptable for most sites, or Mozilla, which is slower but more compatible with newer sites.)
You can also find IPK packages for about any application you might imagine, and if you can't find something specific, you can compile your own (I'm in the process of learning how to do this, trying to compile Fluxbox 1.0.0.)
Then you have the newer distros like Debian and Zubuntu, the possibility of installing several ROMS in a SD card and running the system from there without touching NAND, etc.
Frankly it's too bad popularity has faded for these extraordinary devices. Shame on Sharp for dropping the Zaurus.
