I blame the fact that my attention span is too short, and that I like Kontact too much :) Whereas Gnome didn't like Kontact much at all.
The other thing that bothered me was that I couldn't find a way to make programs open on specific desktops, or at specific sizes (etc). It might not sound like much, but for a geek who likes some sense of order, its a big thing. :D
Might get round to posting some screenshots of my desktop(s), just as reference to my OCD.
So, looking forward to KDE4 now :)
