Oh, certainly a remote X session via VNC is useful. ((I've been using 
VNC for years. I actually prefer TightVNC because it includes 
compression itself, rather than having to tunnel it through SSH or 
something to get compression).

I'm just questioning the decision to run X on a machine that's less 
powerful than most modern PDAs. Mine has a 250MHzs MIPS (certainly 
nothing to sneeze at, but still not that much of a workhorse) and came 
with 16MB of RAM. Of course, I upgraded to 144MB as soon as I could find 
some more, but still... these guys are more suited to running Samba, 
mail, DNS and DHCP services.

Connections may also be shared. I have even done short interactive demos 
with clients via VNC sessions. Very sexy.
