. . . enough of a hit that the Surface devices are going to be around for a while
Yup. I think you got it. I think both the RT and the Pro have found their somewhat separate markets and will be with us for a while. Having had both for the last week (almost), I just haven't found anything to complain about, but, if Ladyfriend were not coming up tonight to pick up her Pro, I would spend the evening trying to think of something, just so I could be in step with others.
Speaking of which, what I'm really gonna miss is that little Wedge Mouse! Since I already have another bluetooth mouse (MS 5000 Notebook Mouse), I'm not sure I can justify the purchase of another Wedge Mouse. Of course, when it's been gone for a couple of days, I may become more malleable. The advantage I have is that I don't have to "justify" it to anybody but me, and sometimes I'm a pushover.
