Don't mistake 'putting up with' for 'happy with'
Well, if average users are anything like me (and judging from my conversations with many of my fellow iPad users, they are), they will welcome the ability to do full computing in a very portable format. Myriad are the meetings I attend at which someone laments the inability to switch into this or that application to accomplish something or display something that would further the meeting, on the iPad they're taking notes on. If Microsoft's product turns out to have the low learning curve of the iPad and they can ramp up quickly to supply lots of apps, I would switch. I'm a long-time PC user anyway.
