To be honest I think that KDE isn't developed as fast as in the past. It has some features like activities and akonadi which may seem good however I don't know how many people are really using them. I am a KDE user for a over a decade and honestly I can't find a Desktop Environment that will let me do my job better than KDE. I've tested GNOME Shell 3 and Unity but I couldn't make them my default DE. However I see Unity being constantly being developed and new features are being added constantly which gives me the feeling that KDE will be left behind. Only time will tell. What are your thoughts about KDE and Linux Deskop Environments in general?
