Who knows? Maybe it was written by a Honeywell shill. Worked on me apparently.
I will note one other difference which helped sway me to Honeywell is the fact that the Nest requires a battery, while the Honeywell requires "bus" power. I actually didn't have a "C wire" set up before I installed mine, but it was trivial to climb into the attic and re-purpose the fan control wire to instead provide constant (24VAC) power.
Granted, changing thermostat batteries wasn't really at the top of my pet peeve list, but I did read that the Nest has the potential to suck batteries dry too quickly. Any opinion on battery life?
Nest uses your HVAC's power wire like other thermostats. There are no batteries to replace.
It has a permanent internal battery, charged by the power wire, which allows it to stay active in a power failure and to use more power than some systems provide when you're interacting with its screen. So there's no real difference between the Nest and the Honeywell in terms of power or installation except that the Nest has a built-in rechargeable li-ion backup battery.
Nest does have an internal battery than can be charge via a USB port if you ever need to. I bought my Nest used off Craigslist (substantial savings) and have never had any low battery issues. It's bus powered, but the battery smooths over power disruptions.
