Me, Me, Gimme, Gimme :D I'm sorry, but using KDE 3.x now feels like I'm using a 'Fisher Price' product (no offence meant to KDE 3.x devs).
KDE 3.x was an excellent desktop for it's time, KDE 4.x has raised the bar for me. Yes I know it still lacks in many areas however, it's stable and usable enough for everyday use.
