  Hey, this must be the coolest tool from a long time, Imagine this On the "Machine 1" you use the digital pen instead on a mouse and when you say copy on a file, the in-built flash memory on the pen will also copy the file (using bluetooth), On "machine 2" use the same pen and browse to proper place and say paste :) urlLink http://news.bbc.co.uk/2/hi/technology/3774747.stm
