Dragging and dropping was supposed to be good, and in WPS it was - but in Windows, I never know what exactly I'm dragging around and what it will be when I drop it. So I don't do it - and it ends up being a "better DOS", even after all this time. XP is no better, although it has no DOS and I'm sure you can drag and drop a lot of things - it never occurs to me to do it. The icons are pretty, and if you are OK with Explorers and Pads and Classic Views, it will stay out of the way.
KDE is so much like Windows that you don't really use its features, pessimistically assuming that chaos is everywhere. But it sort of works.
