We’ve wanted headed mounted display technology to take hold for a long time. Gizmodo recently compared two consumer models: the Zeiss Cinemizer ($400) and the Myvu Crystal ($300). Unfortunately the resolution of HMDs has gone nowhere in the last 10 years. These two devices only support 640×480 and are aimed specifically at iPod users. With computers getting smaller and higher resolution, we’re surprised that HMDs have not followed suit. Why isn’t someone going to market with a 1280×720 headset? If you really must choose one of these two, we’d recommend the Myvu. It has composite input so you can hook almost anything up to it.
