Tom gets caught out trying to cut-and-paste between different computers. I do that the whole time. Very frustrating. The clipboard shouldn't be on the computer, it should be stored on a ring on my hand so that when I copy it's uploaded to my finger. And then I change computer, and paste, it's downloaded from the ring through the mouse and onto the new computer's desktop (or wherever). I mean, of course. Bluetooth could be cool for this.
