Multi-head Meets the Laptop
PARENA writes: "Estari comes with a Dual-Screen Laptop! "A what?!" Yes: Dual-Screen. In fact, they are 2 15" TOUCH screens. According to TwoMobile: 'Unlike electronic tablets, the 2-VU(TM) allows users to view two full-page files or documents simultaneously. Users can page through two books at once, or take handwritten notes in a notebook on one screen while paging through a book on the other screen.' Sounds pretty cool!"
This thing has already been dreamed up by Apple more than 10 years ago.
See their Knowlege Navigator QuickTime movie.
It is a laptop, it's got a CPU and memory and screen, and it takes USB keyboard. More specs: http://www.dualscreen.com/specs.cfm
Have them carry a little 14-15" LCD monitor with them. There are some that are very thin and have detachable stands. ViewSonic and Sony both have some new ones that are only about 1-2" thick and the casing is not much bigger than the screen on either side. In any case, it's probably just about as big as a laptop and could be carried in a similar bag for a presentation. Not bad compared to the cost of a projector that small.
