I don't work for West Elm or Nike, but the work I do as a GIS consultant has some similarities to the scenarios highlighted in the Microsoft Courier demos below. The iPad seems like a nice media consumption device, but I still can't get past the fact that its basic interface is the same one I have in my pocket, only larger. I like the direction Microsoft is moving here, something focused more around work than play as these days I tend to do much more work than play.
From what I've read, Microsoft plans to release these in the fall of this year. Think they'll become a hit? It's supposed to be about the same size as an iPad, only split between two screens. Also, earlier demos showed the ability to flip the unit over on its side and use it more like a traditional laptop with a "virtual" keyboard displayed on one of the screens.
