It's the best possible headset that could have been built with the technology at the time, but the technology at the time was insufficient for the experience that it's designed for. It still has its uses (it's incredible for watching movies and doing work in environments where you don't have a suitably sized monitor), but I agree that it's not a product anyone other than extreme enthusiasts should buy.

I certainly hope it'll get smaller, cheaper and more efficient. I would love more resolution, of course, but I'd be more than happy to keep the existing resolution if the actual ergonomics were improved.
