After saying I wasn't going to get it because I didn't care for the consumer preview on my laptop, I thought 'what the hell...'! I've always tried to keep up with the latest OS's and even though Windows is very much a tertiary computer platform for me, it is only $40. One of the things I didn't like with the Consumer Preview was because of the fact it went on a virgin drive. That meant just basically the defaults, which were not all that impressive.
But now that is is on my Acer laptop as an upgrade to an existing setup, it is a bit better in real use. Yeah the 'new', 'metro', or whatever they are calling it isn't all that great imo, and the apps that come with Win8 are about as simplistic as can be, more like tablet apps than anything else. But thinking of that Metro UI as a big honking task bar makes it pretty useful. I thought I would miss the start menu, but haven't since I tended to use the taskbar and desktop icons instead.
One thing I really do like is that if you have a dual-screen setup, and choose to extend the desktop, the Metro UI will be on one and the somewhat classic desktop will be on the other. That is handy. One oddity is that unlike Apple, updates to apps are not notified when available (might be optional, don't know yet). There were quite a few updates available but until I actually went to the MS store, I didn't know it.
So far all my apps seem to work fine although the damned DirecTV2PC app wants to be activated again. That is one hinky app! I'll get around to that at some point.
EDIT: Damned app! Got it 'activated' and now it says the laptop it has been working just fine on doesn't support some idiocy the programer stuck in the piss poor application. This app has always been one of the hinkiest apps I've seen in a very long time.
Overall Win8 is no more or less than what I thought it was, basically Win7 with a different skin in appearance and operation and a bit faster.
