This is a gimmick / niche item. There is no practical use for a double sided display with different screens on each side that is not better served by using a $500 40" + TV, $200 projector, or $100 external display.
I have been waiting for this one for a while. The smaller size won't cut it. I do a lot of small meetings (me and 2 - 3 around a small table). This will be great for looking at maps and / or prezi / ppt presentation without whipping out extra stuff.
Ok. that all said, I still don't know where to find this new model!
