The End of the Spec Wars
As long as we've known it, computers and the related areas have largely consisted of large pissing contests where in the end, nobody really wins. The end of these wars is coming, at least for mobile, because technology has begun to become so responsive and accurate that we can't notice any differences going upwards.
For an example, simply look at current cellphone screens. There won't need to be any more variations of display once all the major display types have 300ppi+ screens. Both the iPhone and the HTC Rezound have gorgeous displays, and about the only way to upgrade them is by putting in SAMOLED+.
Processors are beginning to be less of a concern as well. With devices that have their software specifically optimized for the hardware (i.e. iPhone, Nexus, WP7) the ability of the software to innovate will fall behind the processors' power. Already, we are seeing this with the iPhone. If you have a 1gHz dual-core processor that runs an OS smoothly, it's better to use that phone than an underutilized quad-core one. The power doedn't matter; it's the accompanying experience.
The only thing left to regularly brag about now is the software; this is where the battle is shaping up to be fought. No longer will a phone be based on a set of numbers; it will be based on its software and how well it runs it. Software innovations will be king, and Apple and Google have a hand up with their already-strong ecosystems. Software is the key.
The winner will no longer be based off a spreadsheet. It won't be how many cores something's rocking. It's how the phone interacts with its software and the user to provide a cohesive, enjoyable experience.
