Up and down
Microsoft do seem to suffer from big company itis at times.
They rushed Windows 8 when 7 was going great guns, diverting devs off Windows Mobile at a time it just had a chance to succeed. Result: People hated Windows 8 and Windows Mobile died from neglect (MS owned Skype at the time and didn't even have a native skype client).
And now they've rushed 11 when nobody needed it. All they had to do was wait until spring - the PC makers would have been happy as it would have been a boost at a lull time of the year.
Crazy.
Having said that I quite like it. Though I got on with Win 8.1 (not even i'm sick enough to have managed to like Win 8).
