DonaldP asks: "I've been making head-mounted displays for wearable computers for a couple or three years now; I think my latest and greatest 3rd Generation display is a big step ahead! It fits inside a normal-looking pair of sunglasses. Why would I do something like this? As far as I know, this is one of the only ones available out there - the only others that come close are made by MicroOptical Corporation, but it's been years and you STILL can't actually BUY any of their products. With large companies like Xybernaut holding plenty of patents on wearable computers and going strong, is there a place for my little one-man company? Any tips for making it on my own? Or is my best hope to hook up with a giant?" I've been waiting for a nice and portable HMD for years, and this has the advantage of not making you look like a Borg reject (although some of you might like that look). HMDs still have a way to go to be practical for everyday use (many still require perfect vision or contacts because they are clumsy with glasses) but I'm sure these drawbacks will be fixed with time.
