My vote goes to openSUSE. It is well integrated and has the best finish, because they make sure all packages work well together. And administration could not be simpler than with YaST. Soon there will be a secure web interface for YaST and you will be able to service these converted machines remotely, if you need to.

I recommend trying OpenSUSE on your tablet. I am not sure about Fujitsu, but my Lenovo X60 Tablet has been working fine with digital pen since openSUSE 10.3. The openSUSE guys have been very active in developing new support for tablets. Check out this page: http://en.opensuse.org/TabletPCs#Configuring_Your_Tablet_Device

With the beta version of openSUSE 11.1, which I am now testing, I can get even the touch screen mode of my MultiTouch tablet working. Add to it the 3D desktop effects and it blows everyone out the window!
