Is it true that you can access a windows xp proffesional from a zaurus?

You can with pdaXrom.... install rdesktop.

You have allot of questions, and that is cool. It may be better to post them all in the same thread though in the newbies forum.

you can also use vnc

As long as you can network our Windows, Mac or Unix machines, you should be able to move data in both directions.

Like me, I can mount both Zaurus and Windows machine on my Mac desktop via Samba, and I can move files among the three systems. However, there is a file size limitation to transfer files from my Mac to myZaurus.

So as not to confuse, rdesktop (though I can't remember if it works for all sharp roms) is also available on the sharp rom and I would be surprised if OZ didn't have it.
