The more I think about it, the more the smart phone/tablet like interface makes sense.
Kids are using smart phones and tablets now as computers (games, internet), so it makes sense to make the computers interface similar.
I'm not saying I like, just that I understand.
EDIT- wait, is Windows 8 for desktops.. or just for tablet PCs?
If you install the preview 'beta' Windows 8 ISO, will it only work for a certain time and then be dis-activated by Microsoft?....
edit edit..
And I question the need for 'all new" operating systems every few years.
XP came out in 2001 and Vista in 2007.
Why Six years? Because XX was very popular. Users liked it.
Windows 7 came out in 2009 because Vista was not popular.
PC sellers kept offering XP downgrades on Vista PCs because nobody wanted Vista over XP.
But Windows 7 is universally popular and they want to replace it just three years after it came out?
They should have called in Windows TP (for tablet/phone) or something... and kept Window 7 their main laptop/desktop OS.
