Linux as a technology is very competitive. It's the implementation of it that needs to catch up. The software needs to be organized around the hardware and tightly coupled to services. That's what Apple is. The iphone/ipad, the iphone os, and itunes + Apple app store. It's all integrated, that's the magic. I can't see anything inherently preventing Google/nexus/Android or Nokia/n-series/OVI from surpassing Apple in this regard. They have the resources, they just need the direction.
