I've said this else where before but I don't have time to track down my old post, but essentially, the advantages of a Nexus devices aren't the cutting edge hardware components, it is the cutting edge software that take full advantage of tried and true hardware. I would rather have a device where the hardware inside has been around long enough that the software devs have had a chance to run their code on the actual hardware and optimize the system to run beautifully than one in which I'm running hardware with mind blowing specs but the hardware doesn't know how to efficiently run the beast... it ends up being a waste and only for bragging rights and not true performance.
