Why do we accept the judgement over success (or not) from some unspecified "people"? I'm using Linux as sole desktop (1) since 0.9* (exact version is long forgotten) and judge Linux as a long-running success. I'm tired of reading about the question if the year of Linux-desktop comes, the first decade of Linux-desktop is already history. World domination may not come the next years, but this doesn't devaluate the successfull running Linux-desktop.
(1) several years ago I had booted for non-desktop use a specialized game-loader (aka Windows ;-))
