Hi
As I use my laptop for more and more full screen work I find myself alt-tab just to read things like match scores, keep track of an IRC conversation or follow items on a to-do list. While this is not exactly debilitating, it gets a little annoying and its not practical for me to carry around a second monitor. I have used a tablet a few times with a few software hacks to export a second screen via vnc but its both laggy and impractical. My idea was similar to what Lenovo had on a laptop a few years ago, a pull out screen that acted as a second monitor.
Maybe reusing a 7 inch tablet screen, a smaller smart phone screen or more practically a netbook screen. Something that you can literally hang off my current laptop screen and plug in via VGA.
Cheers
Tom
