Hi there
I've just seen a demo of a wireless monitor using the Intel Graphics wireless adapter.
Brilliant -- and this type of technology can turn your PC into a tablet !! giving you the ultimate best of both worlds.

The current wireless monitor is too large to be portable (it has all the same functions as a modern TV with all the various connections such as HDMI / VGA (traditional) / built in digital TV tuner etc plus the wireless adapter.

A smaller portable variant with a touch screen is due to appear -- now that's what I'd use at a shot -- a laptop with a detachable screen so I could use one of these wireless monitors.
