However, that io.js ships with v8 4.1 is quite a large step ahead for dependants, not just for language features, but also under-the-hood stability and performance.
Of course, there is also everything that node 0.11.x has, plus a release schedule to match Atom's own release cadence. :)
I found this line in The Verge's interview with Tony Fadell (Nest's CEO):
"And if the Protect senses a carbon monoxide problem, it’ll instruct the thermostat to shut off your furnace."
That is of utmost importance. That alone makes it by orders of magnitude the safest carbon monoxide detector made. The integration is going to make all the difference.
I want my future home to be setup with this stuff.
My only disappointment: It does not report back temperature to the Nest thermostat.
