Here's a piece of video history that is not well remembered for very good reasons. It's astounding how much effort Hitachi put into this for what they got out of it - but I speculate in this video as to why that was. If anyone has an M2, get in touch! Would love to compare it. (This video has audio issues due to air conditioning noise I couldn't fully eliminate, and several voiceovers I was forced into due to factual errors. Sorry!)
