Many cell phones will have a hard time adopting it, because it's not really compatible with touch technology. A finger or stylus over the 3D image ruins the 3D illusion.

So you can have a touchscreen or you can have a 3D screen. 3DS gets around the problem by having one of each, but I don't think many people will be interested in having a phone the same size as a DS. 

So the only viable way to do it is to go back to the ol' keypad and trackball phones. I know if I had a choice between a bulky phone with a clunky interface and a 3D screen or a slim phone with a slick interface and a 2D screen, I'd stick with 2D. Looking at current cell phone trends, I don't think I'm alone here.

Cause you know...text messages are the shizzle in 3D.

It's really more of a gimmick right now i would agree, unless you are able to convert the Avatar 3D Blu-Ray movie to the cell phone, witch wouldn't make much sense either. But looking at how failry inexpensive and widely adaptable this technology seems to be, and counting in the rumoured fact that the PSP2 might have touch pads on the back it makes it quite possible for the PSP2 to have a 3D screen aswell doesn't it?
