I'm just wondering if the same Metro UI will be used across all hardware platforms. Interacting with the Metro UI on a desktop with a mouse just feels awkward.
And also, Microsoft's prime customers are business users. Can you see Betty the secretary, or Bob the sales manager using this interface any time soon? I think not...
But hopefully it will catch on, as MS seems to be keeping track on shipping the RTM as almost the same product as we are using today.
I find personally that when clicking the Start Menu,and then get transported to the Metro UI, that's it's really irritating. I don't need a dashboard - I just want to open an app.
Hopefully they will be able to cater to both type users, sort of like what Apple did with Lion. A nice tie-in with the iPad like feel, but not overboard.
