This week's much-ballyhoed launch of RockMelt is again getting the tech intelligentsia in a lather about a potential new browser. What they seem to be ignoring is that the battle has already been won and lost: the best case scenario for RockMelt is, romantically, they become a plucky cult favourite like Flock before running out of steam and sinking into obscurity; pragmatically, they are doing things so well and advanced that they are bought and assimilated by the companies who have already won this space.
