+Robert Grasböck yes I have to hand it to the Kubuntu package team, they really get the updates out fast.And some of the Ubuntu packages are not usable in Debian so I don't trust the Ubuntu packages are even pure Debian anymore.
It's posible to run (and switch to) every application extremly fast just with your Keyboard. No more wasting time moving your hands away from keys. No Alt+Tab Tab Tab Tab ... also working with K-Apps without touching the mouse is posible (mostly)
Everyone I install Kubuntu onto their computers says either "Wow!" or "I love it!", or "This is nice!". It looks good, works good, and people "get it". It's just getting sexier and sexier as time goes on!
