Here's a few pictures, kinda bad lighting right now, but should give an idea for the size. The first one, I have the Apple keyboard (same size as on the laptops) lined up along the right side of the viewable area. On the right is my iPad in it's dock for scale.


Second shot shows Avatar playing at native 1080p resolution.


Last one has 2 720p videos, with just a slight overlap due to the OS X menubar taking up a bit of space at the top.
