It took something as bad as 10 to make me give 8.1 a second look. I thought the tiles and the Metro stuff was bad (and it is), and I thought it had to be the worst Windows ever. Only after 10 came along and I realized how good 8.1 had it in so many ways did I think to go back and try it. With aftermarket addons to remove the ribbon and the tiles, with the apps removed and Metro locked out, it's not bad. It takes some effort to get it not bad, but now I can avoid 10 for six more years before leaving the WIndows world behind for good.
