Hi.
My sl6000 came to me in december 2004. I was one of the lucky ones to buy at Ebay when the prices where extremely low (don't even dare to name the price). At the moment I use the Sharp rom. Not because I like it but becasue it uses all the features of the machine. Since I'm not experienced in programming, the OZ roms are not within my reach. I do experiment with the 3.5.3, but there are too many problems with it for me to abandon the sharp rom. The problem with the sharp rom is that it tries to automate too many things (e.g. collect all audio files in one list, maling it impossible to distinguish between different tracks).
In addition to the qpe filemanager and terminal, I've installed qpegps which I use with a Fortuna Xtrack CF GPS receiver. Works perfect. Sometimes the Xtrack is not recognised. I take it out the zaurus, change the switch and put it back in and restart gpsd, it works again (something like a reset action by changing the switch).
Furthermore I've installed TextMaker, which is way better than Hancom Word (but it is not free).
I'm still looking for a nice case. Unfortunately Piel Frama (spain) does not produce cases for the 6000 (yet). The ones for the older models are lovely. I am trying to get in contact with them to find out if there is a chance that they start making cases for the 6k as well.
What do I use my Z for? I travel a lot with public transport. The Z is brilliant to make notes, answer e-mails, listen my mp3's, read documents, make minutes of meetings. Also I use it to track hiking trips and I'm going to use it for tracking ice-skaing trips I'm going to make next winter (wit qpegps).
The best of the Z6k: linux, screen, speed, keyboard, wifi, robustness, expansion slots
Missing: a nice belt case
