Welcome to AF, Paulanater.
I played with Win8 on a test PC. I can see its usefulness on a tablet and maybe an entertainment center PC. I do think it is uuuuugly.
For a desktop, it makes no sense and just encumbers.
Intel has tick-tock. Microsoft has tick-flop.
Win95 - great
Win97 - flopped (not even released)
Win98 - nice
WinME - flopped
Win2000 - nice (I'd argue this doesn't count since it was a rushed version of XP to get the "2000" moniker)
WinXP - great
Vista - flopped
7 - great
8 - I expect it to flop in desktop markets and not do so hot in mobile markets, maybe "ok" maybe flop
9 - Like 7 is to Vista, 9 should undo the mistakes made with 8.
I'm thinking 7 will stick around for many years like XP did.
