Well, strictly speaking Intel isn't shipping 32nm medfield yet either. They may have a lead, but I'd be very surprised if it's more than a few months. Meanwhile the ARM side isn't standing still, they're already working on 14nm.

I did, it doesn't seem to share your optimism ("It is conceivable that Atom on 32nm could get very close to the power efficiency of competing 40nm ARM processors").

I was referring specifically to the crippled IA32 ISA. Things are a lot better in long mode, or even "x32abi". The Atom implementation in particular (lacking out-of-order) seems to be outperformed by the competition even in x86 space.

But anyway, if they manage to produce something that can idle for a week or more on a ~1.5Ah cell I won't complain ;-)
