Well, Bluray sucks big time. Not exactly the technology, rather the company (Sony). These people are always trying to trap the consumer into having to buy their products by making them proprietary.
Remember the betamax? They made the Betamax and wouldn’t license the technology to anyone. Their thinking was they could then sell the thing for whatever price they liked with no competition from anyone. Unfortunately for them, the company that held the rights for VHS was willing to license it to everyone. The end result was that when people went to the store for a recorder, the Betamax was lost among the dozens of VHS recorders on the store shelves. We all know what ultimately happened which was the Betamax was relegated to history’s junk pile, all due to the greed of Sony.
Remember Microchannel architecture? IBM tried the same tactic but lost out to ISA.
Sony is trying to pull this same crap again with their Bluray technology and if successful, they will be the only ones selling the players and they’ll be able to charge whatever their amount greedy little minds come up with.
They’re also attempting to do this with a proprietary competitor to the next generation USB standard.
Anytime there's only a single source for a technology, the consumer is the one that suffers.
