Not necessarily a dearth of content..
If consumers are looking for stereoscopic material, then yes, it's going to be difficult.
However, if a PC is linked up to it, suddenly most 3D games and modelling apps become playable stereoscopically. For some games it isn't a gimmick - it's a genuine new feature. Unfortunately all 3D technologies have some disadvantages.
The fairly cheap Zalman 19" monitor I have is not a great 2D monitor, but it manages. In 3D mode the vertical resolution is halved, the vertical viewing angle is small, positioning is key (it's currently on top of a foot of books) and some games suit it better than others.
The key is when it works, it really works particularly well. There's proper depth perception, and images floating in 'front' of the monitor are very impressive.
Of course, it still depends on decent content. Avatar was an impressive 3D showcase but a subpar film. Alice in Wonderland's 3D wasn't as good, but the film a little better.
