You can actually get a 3D monitor for a fairly affordable price. They cost about $300 on NewEgg. Granted, these monitors require you wear some passive polarized glasses, similar to movie theatres, unlike the $3000 TV screens they're talking about in the article. (These lenses should not be confused with the shutter glass technology that has been around for awhile, nor with Red/Blue glasses that you can use with standard monitors and NVIDIA's 3D Vision Discover [http://www.nvidia.com/object/3d-vision-discover-main.html] tech.)
Speaking from experience, once you've gone 3D it's hard to go back. Being able to see around the polygons you're staring at is really cool, it gives games are a true sense of space that really gives you a better feeling of what's going on in the game. Unfortunately, not a lot of games are properly compatible with 3D yet, they usually have their Z-Buffer drawn wrong somewhere, with certain things like HUD indicators drawn in 2D over the 3D screen, but maybe the introduction of the Nintendo 3DS will heighten developer attention.
