it seemed to run better than 4.2(and all other 4.x before that) did but for some reason my kwin cept crashing every time i logged into kubuntu, so i just decided to remove it, and audio for kde programs was basically not working, was kinda lame.
so for now just running back on ubuntu 9.10, some weird problem with my vid card drivers going on so i may try out opensuse for the new kde version.
it was a nice update though
