Wow- a lot of stuff to adress here.
1. The glasses fit over prescription eyeglasses. I've worn the glasses over glasses a lot more than wearing contacts.
2. SLi necessity- I have been using this with a GTX260 Core 216 and it plays GREAT.
3. The Economic Times: The best time to introduce tech is as soon as it works- the economy has nothing to do with it. The people who can't afford it shouldn't buy it, those who can will if they like it.
4. Marketing: I can't put it any plainer-
I don't care if you buy this or not. I reported on this because it's cool tech I think all 3d gamers would like. If ATi puts out a similar set of glasses tomorrow, I'll change my recommendation to "You should pick a brand and get this- changes everything". Ditto for the dual pane monitors if they fix the issues.
5. Cost: I said "for what it is" entrance cost is low. I didn't say "the cost is low for everyone".
I will say you can't spend the amount of money it will cost to do this in any other way and get 1/100th of the return on your investment in terms of 3d gaming.
6. Eyestrain- there are some VAST improvements here over the old tech. (this was my main problem with the old tech, and I love this)
Most of all- I'm not expecting anyone to take my word for this, or even have my preferences. If you're interested at all, read the reviews and go see it at a store or friend's house.
I'm just telling you for me, this is a VERY big deal, and I won't be without it. I'd spend the money this costs without thinking twice to have this.
I won't be writing an article about this like ChrisRay will be posting at B3d, but I'd be happy to answer questions about my experiences with it starting tomorrow. (and will be more specific in my answers, as NDA will be expired)
I hope some of you get a chance to try this as well, it's a lot of fun
