That's impressive, but I don't really have any use for a 5 Watt CPU. I've literally just pulled the trigger on moving to a 15inch MBP because of the 47 watt TDP of the parts. The challenge for ARM is crawling up to 45W, 65W, 90W, 150W performance. Hitting performance targets at the 5W is great for Mobile CPUs, but it sort of belies the fact that they're not ready to play in the real laptop market yet. Looks like it'll be chromebooks for the foreseeable future. I certainly don't see Apple being able to offer anything compelling with this.
