Sharp zaurus arrived today
...thanks, Sharp! It is c3000 model. I already booted it, but it speaks japanese (and I do not).
Yesterday I played a lot with fortuna GPSmart GPS receiver. Its user interface is almost unusable (still better than Billionton, but...). Tts radio parts seem to work very well, and it is actually usable. I was riding bike with GPS around my neck, and it basically did not loose satelite connection. Good.
