I think it would be great if, along with the AVCHD , Ady creates a 720p .mkv encoded in x264. The quality is extremely high, though compressed, and is playable in many different media players, on any computer that has the proper codec, as long as the computer can keep up with HD playback. It also benefits from a smaller file size; a 2-hour .mkv in 720p usually can fit on a single DVD-5 for storage. I would definitely want the AVCHD for the ultimate quality, however, I don't even have a blu-ray player yet, nor an HDTV, but I can play .mkv's on my pc and they look incredible. It would be a great alternative for folks who don't yet have blu-ray capability. On the other hand, I think AVCHD will play on the pc as well. Just a thought - I'm a big fan of .mkv at the moment.
By the way, I was playing Trivial Pursuit earlier with my girlfriend, and the question she got was "What are the odds of navigating successfully through an asteroid field, according to C-3PO"! (The category was space). I thought that was hilarious. I wished it had been my question, since at least that was one I knew.
