Okay, HP and Dell, both sell servers, whats your point. A lot of companies sell magneto optical drives, it's real popular with MRIs and servers, but you won't see it anywhere else. However, in order for any medium to become popular, it has to have more than just hardware companies saying I'm in? Remember dvd-ram? Panasonic's idea of what dvd should have been, turned out to be a dud. What you are saying is that it if something happens, and if something happens after that, then this might happen, that's a lot of ifs, and I seriously doubt that blu-ray will be the medium of choice in the next few years. Will it be cheap to produce? Sure, but it's cheap to make a lot of things, doesn't make it infallible either.
Shivers: what would you prefer to archive on? Hard drives? Floppies? Or will you go buy me a 500 dollar tape drive and 50 dollar tapes?
