I was at CES and I saw them. I agree with the above poster that the gizmondo report sounds fishy to me.
The shutter glasses sets are the only ones worth considering, though. The sets with polarized glasses reduce the resolution by half as they have alternating rows of opposite-polarized pixels, and can not show the full-HD 3D stuff at HD resolution. Maybe he's talking about that.
Also, with the Samsung shutter glasses set, when I tried on the glasses (after picking them up from a stand) it took them about 3-5 seconds to sync with the displays and they were out-of-phase at first. So maybe the reviewer put the glasses on, saw it out of phase and said "Gak!" and immediately took them off. That said, I also tried really hard to make the glasses lose their sync again while I was wearing them by turning around for a few seconds, looking at the ceiling, etc. and I couldn't do it. Once they were locked in sync they stayed that way and the picture was really quite awesome.
So... I came away from CES thinking this 3D tv stuff is for real, and works impressively well.
