KDE is definitely a nice desktop environment, though I confess I'm still a big fan of KDE3 (and even Windowmaker). There are still a couple of things I just don't get though, so there's still some room for reason to prevail as the KDE4 platform matures. (I'm using opensuse 12.3, for the record).
1. It annoys and scares me that all of the Plasma desktop widgets seem to have an option where they can be controlled remotely. I absolutely don't understand the point of that, worry about its security implications, and find it a waste of disk space.
2. No offense (and this is coming from a guy who prefers KDE over Gnome) but a lot of Plasma desktop applets are really useless. I can dig the newstickers, RSS feeds, comic-of-the-day stuff, etc. But what's up with the red bouncy ball? What's the point of that?
3. I'm a bigger fan of the KDE4 apps than I am of the Plasma desktop (even if I do respect and agree with how they've made it into a system that can produce different screen/work environments for tablets etc. instead of the Gnome "stuff-it-down-your-throat approach; Win8 as well). And there are some great KDE4 apps. But Kontact is not one of them. I anxiously install and run it on every new desktop, thinking "this time, it's going to work." And it never does. Kontact on my opensuse box regularly gets hung trying to open a "choose a file" dialog box (say, if I'm attaching something to an email). I blame its ridiculous database and akonadi semantic crap foundation. I find myself using Sylpheed or Thunderbird, but more often I just go to Mutt, which remains unsurpassed for the power emailer. But Kmail/Kontact has so much promise. Why can't they ever get it right? (by the way, a QT alternative I like more and more is Trojita. It's standalone, super fast, and interesting.)
