Does it actually look like you are watching something displayed in front of you? or more like you are actually watching something projected directly into your eyes?
That's difficult to say, as your eyes have to acclimate, the first time it's quite exceptional, it seems that you are looking at a very big screen or a canvas. But after some time, your eyes will hurt, as you don't have the habit. And I would also say that watching it for more than 2 hours is impossible. It's more like a toy for us big kiddies, that was also the reason I bought it

I got mine for 300$ at eBay, did not buy it new of course. My model was priced at 2000$ when it came out, there are different models existing of the EyeTrek.
