To me the problem is more marketing those screens. I have yet to see one of them physically and that is what makes screens sell. Maybe they could try to put the screens on big players' products, if even just to get their name out there and make people aware of their existence.
Another thing which I'd personally buy if done right, is a portable screen. e.g. a small screen, maybe about 10" which is powered from usb, to e.g. attach to your laptop. With a reasonable price tag, I think it'd really sell!
