So following the advice of Scott Hanselman, I bought a TouchScreen Mimo monitor.  VERY cool.

Checkout out my desktop now!  4 monitors (I bet 5 is not far off!) 

    2 – 24 inch
    1- 21 inch
    1 – 8 inch touch screen

One piece of advice however, if you are going to buy one, spend the extra money and get the 30 bucks and get the Mimo 720-S instead of the Mimo iMo pivot you see here.  I really like the monitor, but the stand for it is too high and not adjustable.  If you want to use it as I am here on the desktop as a IM / Zune / Windows Media Player window, the 720-S has a better stand system.
