Hmmm, interesting, Rene...
In meantime, my current Zaurus replacement is my Pandora Rebirth from Open Pandora, also made in Germany...
In fact, my new 1GHz Pandora was just shipped from Germany to me this morning!....so, can't wait to play with it soon...
Pandoras are great, bit larger/thicker than Zaurii, but not too much, very pocketable...have built-in wifi and 2 SD card slots....and can run Debian or Angstrom, etc....so, very flexible....
