On a Latitude 10 running Win 8 I find that a travel 3-port USB hub and travel sized mouse and keyboard is rather efficient. Of course I found that for a lot of things on my Android tablet a mouse made a world of difference as well. The reality is that as we start pushing these things to be our main screen rather than an accessory screen, the interface size being 10 inches or less makes working with detail items difficult. Whether it's Win 8 or Android, if you have to select from a multi-item list a mouse is still easier to use than touch.
