yes, I use pdaXrom...
I have 1.0.1 on my 760.    I use it for the following, some more than others:
  (1)  browsing -- (reading in bed), firefox/dillo
  (2)  reading -- web pages, newsgroups, ebooks, pdf (argh! bad fonts!)
  (3)  chat -- terminal ssh to remote box to IRC/IM via irc gateways
  (4)  games -- mame, lgeneral, nethack, xboard, xu4/exult
  (5)  music -- mp3s, two 512mb SDs (rock/moods)
  (6)  admin -- remote terminal from Z to remote unix boxes, vnc 
  (7)  programming / dev -- perl, python, C/C++, QT (tcc for arm yet? Ch?) gcc/g++
  (

  emulators -- see mame above... hatari/stonx/stella, xmess (dosbox, bochs, qemu, anything) 
 pdaXrom is a mini laptop for me.  The hardware isn't as powerful as I would like as a min --
  800x600, 600Mhz cpu + (+FPU?), 256mb ram ... built in wifi, 20GB min disk.
     *BUT*
  This is more than sufficient for doing the above FOR NOW -- while the specs I want/need
  become available.
I use the Z as an archive of my files and my work.  I can rsync my files to and from the device.
I have my code with me any any and all times.  Grab and run... etc.
I appreciate the capabilities of having a full / native linux.... native sdk, etc.  cross compiler is also
very nice for taking some of the load off the Z.
The reason why I use and support pdaX is that it provides the platform of what I need --
  linux, X, gcc...
I don't need PIM, but there are some programs out there to do that.  xdia is very nice.  gimp runs,
but is slow.
