Hancom Word and Sheet seem to work okay, I haven't tested them extensively, but the load up and are usable. I have'nt tried presenter.
I am mostly still playing with my Zaurus, Zynergy seems to be the most useful on a day to day basis, but I want to get OZ sorted. Main problem is connectivity, USB to my laptop is too much of a lottery even with the old hotplug installed and we won't even mention the "whenever I am in the mood I might get the routing right" feature !
