I don't know if a reinvention there is needed. I have an iPhone and a 15" MBP but probably the most useful productivity improver I have is an almost weightless Bluetooth clicket keyboard that I carry around. If I need to type something like a document on the go, it often turns out that it's much easier to simply put the keyboard on my knee, put the iPhone in landscape on a surface in front on a foldable bit of home made plinth, and rap away at the keys at four times the rate I could without one. Of course iPad users look at me oddly and go back to touching like buttons and watching videos.
