While I definitely appreciate having faster speeds/more cores etc etc, and perhaps I wouldn't accept a trade-off with power/performance until the power starts sapping the battery life quicker than I can cope between charges (i.e. 12-24hrs, depending on use), I definitely think there'd be a market for a slower CPU that uses new technologies to achieve significantly greater battery life than its faster brethren. Unfortunately I suspect most of the battery life goes on the screen, and not the CPU..

The whole point of having multi-core processors in mobiles is to aid battery life...
