3M Canada let me borrow one of their 27" multi-touch monitors. It's a roughly $2000 display, but it opens up so many possibilities. It comes with a great stand that let's you tilt it back until it lays flat. It obviously works great with Windows 8, but let's be honest, Windows 8 isn't exactly going to get too many people excited.
What about Android? Well fire up Android-x86 (www.android-x86.org
) and take advantage of the Play Store's games and education apps! Play multiplayer, multi-touch games. Laying the monitor flat for some air hockey was pretty fun. Google Maps on a big touch screen was awesome.
I'll have to try out even more, but I'm really liking this display. The display has VGA, HDMI, and even DisplayPort. There are built-in speakers too but they're pretty weak and tinny.
