The corporate world long ago embraced the notebook PC for its numerous advantages over desktop machines. Alas, increased mobility naturally comes at the expense of some pretty useful features found on less-portable machines. Chief among trade-offs is video support for multiple external displays.
This may not affect everyone, of course: How many folks need to simultaneously drive two (or more) external video monitors from their notebook? Of course, if you've tried to negotiate a way to run a multi-monitor information kiosk from a single notebook, you're one. Likewise for the fellow starting his dream career as a day trader using a laptop (OK, perhaps this is a bit of a reach.)
The solution for these people is Village Tronic's VTBook, a small PC Card for your notebook that can enable the road warrior to set up their own multi-display configuration -- perfect for setting up that presentation kiosk, day trading station, or, heck, portable video surveillance console.
For perhaps a wider audience, the little unit can also do wonders to help older notebooks stay in the game. For instance, it can support external projectors with ease -- potentially with higher resolutions than your in-board video card. HDTV output is no problem, either.
