Well KDE4 definitely doesn't have enough yet. I looks like a KDE desktop (once I take Oxygen out, it looks to Gnomish ), and it feels like a KDE desktop, but it acts like some sort of XFCE/KDE bastard child; it's like I'm in KDE bizarro world or something. Oh, and the menu; damn, that thing is annoying (you can't change it either).
And still no ports of the best application ever (Amarok)!!!
