I'm no fan of MS: see my comments in general. But your criticisms are a bit too extreme. MS announces EOL dates well in advance of stopping sales [1]. Those who want to hoard up on licences can do so. Windows 7 is still available for sale [1]. Those who did not want Metro could still have used Win 7. In any case, MS listened to its customers and brings back these features in Win 8.1 -- or so I hear: Linux single-booter here.
