I've been reading more and more about Haswell and think it will be a game changer.
It will use 10w of power and some articles are saying it can go as low as 8w; very impressive. I think with this CPU, Intel will get into the tablet market in a big way. I also read that by 2014, Broadwell, the successor to Haswell will debut which will use less than 5w which means it can potentially fit into a smartphone. Again very impressive.
With this roadmap, I am now thinking that Apple might be better off using Intel's CPUs for their iPhones and iPads. That would make more sense than using ARM CPUs for their Macbooks becuase those will not be powerful enough and it would be harder to port over Mac OS to ARM than it is to port over iOS to Intel's CPU.
