Transparent OLED's are a fantastically promising technology. I see a future of handheld devices in which the user interacts by pressing on the back of the screen instead of the front. This allows the screen to stay oil free as well as never having to be covered by your fingers. This would work well from smart cellphones to mobile computers and gaming devices.
This computer is using exciting new technology, but the interface isn't designed for it and there's no benefit to the user for having this technology besides that it is "cool". The only positive I see is that the more OLED's purchased, the cheaper they will become, which will eventually lead to more consumer options.
