It's 2010, surely they're pretty OK by now? All I can find through google is products and prices and tech specs. Actually, holding on the specs for a minute, they seem distinctly underwhelming - the highest res available seems to be 480p, with a lot of "cutting edge" glasses offering merely 240p. What I'm really after is a discussion by people who use or have used them. Should the low resolution be ignored because a screen up-close is very different in some important way? Do they strain your eyes, focussing on something so close? Are they distractingly heavy?
