What I dislike about KDE is that it's mostly ugly. There are lots of small details that are just annoying. For example have a closer look at the taskbar. Or, but that's your own setting, notice the transparency and how it renders text somewhat unreadable, as it makes the text black-on-gray. I'd rather have no choice if I already had something nice in front of my eyes. Apple definitely has this. Microsoft... well... it can be achieved there, too.
