To me, the hardware is the same, and it's not necessarilly the best product that wins. Sony's betamax was better- a superior picture with better resolution.
Why did Sony and betamax loose? everyone else wanted the VHS system and ganged up on poor Sony who kept the patents to betamax.
It'll be the same deal this time around, the group with the deeper pockets will determine the standard. The poor consumer who picks the wrong one, may have a machine on their shelf that no-one wants, just like the people with the beta machines who had to go out and get a VHS system so they could rent videos.
