Does the Mac support multitouch screens in any way? I love using touch with Windows 7 and 8. Especially on Windows 8, the touchscreen finally feels like it's respected just as much as the keyboard and mouse.

So, naturally, I'd want to carry this experience over to the Mac. I've used a Macbook/MBP trackpad, but those aren't the same. They are not nearly as large and usable as a full touchscreen.

So: Does the Mac support touch screens in any way?
One way to get something close, is to use your iPad as a secondary display to your Mac.  In this way you are able to extend your normal desktop onto the iPad and input using touch.
