KDE?

well
despite opinions to the contrary expressed by some,
I personally rather like kde. Gnome is pants on the desktop (imo). And
whilst i've got blackbox,rox,waimea,windowmaker,enlightenment blah blah etc
kde has some things that the other's just dont
i guess it's the same as liking one sort of music but not another

services?
thought i'd seen the back of them with xp
ok
will investigate

many thanks for the time taken
