FYI, I now see that there's a BBS (~500 members) devoted to the Zaurus 5000d. It looks like amount of traffic could at least be described as "moderate"
I am tempted. It sounds like the display is pretty good and I am getting eager to come up with a sunlight-proof 802.11-enabled VNC client for the boat. Interested to know if anyone here lost control and bought one of these!
