As I see it, the world has not moved on on the desktop, rather the contrary, it has been standing still and even gone backwards in many ways. The desktops on Linux seem to have one aim, and that is to resemble Windows as much as possile in order to atract "most users", which for me renders them totally uninteresting. I much rather use a working Windows installation than a broken wannabe, and I think that's what "most users" also think. Linux is good for a lot of things, I'm a Linux user since pre 1.0 days and been using it on a whole range of archs, but these days I'm giving up on Linux for anything else than "embedded" and server use, the deskop environments offered for Linux are just way too bloated, bling-centric and dumb, so my reasons for leaving Linux on desktop are the same now that I had for not liking Windows earlier. Not that I'm that much fond of OSX either, but at least it is rather consistant and somewhat snappy on Apple hardware. Funny to see Linux zealots bad-mouhing alternatives, the irony is striking.
