Bah!
"Nice idea; but do users actually want live tiles on their Windows desktop?"
This one doesn't, and can't understand whay anyone else would either.
"...skips a version number to signify a new generation of Windows..."
But...even numbered Windows releases are always infested with problems of the most virulent stripe and abandoned a year or so later in a flurry of "let us never speak of this again". Look at Windows Millenium Edition (yesyesyes the real millennium was 2001 but you lost that war along with the hacker/cracker one Mr Pedant) and of course Windows 8.
Far better to have dumped 10 and stayed with 9 or gone with 11.
