This might sound like a peculiar question, but is the rMB light enough to use one handed when standing up? By this I mean holding it with one hand, whilst use the trackpad (and maybe minimal typing) with the other hand? I sometimes use my iPad with a logitech keyboard in this way, and it's not too bad, although a bit heavy for anything more than a few minutes. The iPad has the advantage of the touch screen, which I imagine is easier than using a trackpad whilst standing. Just curious and seeing if the rMB can hold its own for a use case that is normally reserved for a tablet.
