Spec convergence is the way forward
Otherwise you end up with 2+ platforms and the public unsure which to go with...so they stand back to watch the market for a leader to emerge. Which slows down the emergence of a leader. Which kiboshes the whole market.
We've all backed the wrong horse at some point, maybe DVDHD or Betamax, nobody wants to be the one who bought the incompatible lemon and sinking precious cash into incompatible kit. Doesn't matter if one system is better than the other, all that counts is the market saturation and direction - then a v2 can make up the missing functionality.
