I always on cold starts, let my truck run until the rpm drops to the 800s, then get moving, cold days maybe 5 minutes to let the engine hit 100 degrees before working it.
How Many of You Warm Up?

I am lazy IS my custom title!!!
That's what I do, even in the summer. In the winter I might let it go an additional minute after the rpm's drop.
I'm always late for things, so I let it warm up until the RPM start to move towards normal, then I pop it in drive, and idle down the driveway. I don't give it any gas until the piston slap shuts up. 
Once the 6.0 goes in, that thing will be treated a bit better in cold weather, hopefully I'll have a remote start by then.

Here is something I dug up on excessive idling.
#2 is what I've always heard.
Myth #1 The engine should be warmed up before driving.
Reality True, the engine must be warmed up, but idling is not an effective way to warm up your vehicle, even in cold weather. The best way to do this is by driving the vehicle. With today's modern engines, and the advent of electronic engines, you need no more than about 30 seconds of idling before driving away, even on the coldest winter days.
Myth #2 Idling is good for your engine.
Reality Excessive idling can actually damage your engine components, including cylinders, spark plugs, and exhaust systems. An idling engine is not operating at its peak temperature, which means that fuel does not undergo complete combustion. This leaves fuel residue that can condense on cylinder walls, where they can contaminate the oil and damage parts of the engine. For example, fuel residues are often deposited on spark plugs. As you spend more time idling, the average temperature of the spark plug drops. This makes the plug get dirty more quickly, which increases fuel consumption by four to five percent. Excessive idling also lets water condense in the vehicle's exhaust, leading to corrosion and can reduce the life of the exhaust system.
Myth #3 Shutting off and restarting your vehicle is hard on the engine.
Reality Frequently restarting has little impact on engine components like the battery and the starter motor. Component wear caused by restarting the engine is estimated to add $10 per year to the cost of driving, money likely to be saved many times over due to fuel savings.
Myth #4 Shutting off and restarting your vehicle uses more gas than if you leave it running.
Reality The bottom line is that over 10 seconds of idling uses more fuel than restarting the engine. As a rule of thumb, if you are going to stop for 10 seconds or more - except in traffic - turn off the engine. You'll save money, and you won't produce harmful Carbon Dioxide, the leading greenhouse gas.

Yep, I always let it warm up. Usually until the temp gauge gets off of 160.

huh, I warm it up just enough to get some heat and then take off...she never drives quite right when she is running cold...
If I can see, it only gets a couple minutes... Otherwise, I wait until I can see, lol.
At colder than -25, I'll let it sit until the temp needle starts moving... But only because the transmission doesn't shift smoothly unless it's warmed up

myth number 2. For example waukesha industrial engines will NOT warranty and engine that is being operated at less than 50% rated output. It causes exccesive oil to get pulled through the intake valves (due to the higher intake vacuum) which will cause premature failure of the cylinder head and possibly the cylinder.
So esentially its best for your engine to drive with the pedal on the floor.

Ain't no trash in my trailer!
I let mine warm up about 10 mins. If its -40 or colder I put it in neutral and let it run for about 20 mins.

I'm usually rushing in the morning, so I just remote start it and a minute later I take off. Ticks like a bitch, though.
