I had the same opinion - I even used windows 7 for years because I didn't really care to configure anything. I switched when I discovered tiling window managers, and application launchers. I think the ergonomic benefits have kinda paid off - since I think using fuzzy searches to do almost everything, splittting and killing my windows as I need them, on as many desktops as I want - is a way more sane user interface than the default floating window + desktop idea, if much less friendly to somebody who isn't expecting it.
