Schuyler Towne did a rundown of current 'smart' locks in November (
http://schuylertowne.com/blog/smart-locks) and included the August (so I won't address it). The Schlage Sense looks an awful lot like Yale's existing 'smart' lock design externally and seems to share most of its features with other existing designs which Schuyler addresses.
The Noke is certainly novel in its form factor (padlock instead of mortice latch or deadbolt replacement) but this really only makes it 'un-pickable' in the sense that traditional pick tools can't be used on it. If the photos on their site are accurate it looks like it has a cammed ball-bearing latching mechanism which should prevent any sort of traditional shimming attack and without a keyway obviously all the hooks and Bogotas in the world won't get you in, but until we get to teak it apart and examine it in detail I would definately not say it is un-pickable in a real practical sense. I won't go into all of the ideas that are occuring to me here (I think at least some veer into Advanced areas) but I will just say that at first glance a limited keyspace for the "Quick Click Access" feature is a likely decoding vulnerability (depending on their implementation), tool-less access to the battery compartment may present a bypass vulnerability, and I won't even get into the insecurity of Bluetooth and potentially unshielded microcontrollers. "Pick-proof", as long as you limit yourself to traditional tools, sure; but, never let a Gecko owner or any InfoSec or serious electronics people at hacker cons hear you say that.
All of that said, 'smart'-locks do have a cool factor and I love seeing them iterate and innovate, I just won't be putting one on my doors any time soon.
