Went to see a demo of Windows 8 and spent some time playing with an offline machine. The desktop is still there. They've just laid this app-centric, iPad meets Pointcast starter screen over it. More emphasis on consumer things like social sharing and media. Multiple program windows on the screen is a show-off point.
Really felt like they were pushing this out mainly for the mobile markets and targeting consumers that were normally in Apple's market. I'm not sure where the business features you need to update for are. Maybe it's better if you use multiple screens?
You probably need 4GB of RAM to be safe with this, so older laptops are screwed.
We'll see. No compelling reasons to update on the demo, but I'm still curious about the Pro Tablet.
I have an underlying suspicion that a few CIO complained that they had iPad users and didn't like two systems in the company, so this is about integrated an expensive but integrated tablet into corporate computing. If the Win 8 Pro tablet is really pricey, then it's an enterprise tablet and we'll have a consumer/business distinction that didn't really exist before.
