I give mine a couple of minutes. I live in Chicago and today was 3 degrees out when I started her up. When it is that cold My tranny takes about 3-5 minutes to operate correctly. if crank it up and pull out the car seems to have power but doesn't want to shift up to 3rd until i am going about 35mph. After running 5 minutes it is fine. It idepends on how cold it is. If you live in Cali or the southwest if you have oil pressure you are pretty much OK to go.

Lights haven't been installed yet, it is getting warm out though so I might do it soon, once I get all these essays I have to write out of the way.

It's 2008 and things may have changed on recent models, but the handbooks I've read for my early--mid 1990s MBs (three vehicles), and for my 1984 Ford Capri 2.8i and a 1996 Golf VR6 (now departed), all recommended starting up and getting moving without delay.
I've seen a report from a Ford engineer who described cold idling as "incredibly damaging". And it takes at least 7 miles to warm up properly, so shorter trips are also to be avoided. You need all those lubricants and coolants to be up to their optimum operating temperatures as soon as possible, and getting on with it is the only way, apart from fitting an engine preheater (which I've done on two cars, with a definite benefit of reduced fuel consumption on one of them).

I warm up for about 4 minutes, I wait until the idle drops down to about 700 rpm then i know its ready to go.

""I dont understand how warming up can be more damaging that driving right away."
I merely quote an expert and trust him. I guess it's because setting the vehicle in motion accelerates the distribution of fluids and heat. Actually, he was quoted by the UK's leading motoring columnist, Honest John of the Daily Telegraph, whose advice I also trust:

Better to start driving and avoiding quick acceleration until you reach operating temperature.
This will assure max protection of all the components.

A lot of good replies, but I dont see how bad it can be to let it run for a bit.
Picture your self getting up at 6 am and right of way, out of bed, no breakfast, nothing, you got for a 2 mile run.... Rather than stretching, eating a nice meal, read the news a little, and then when you are awake fully you go for a run.

warming up
You got people on both sides of the fence who say different things. It is not like we are talking about a desiel. The advatages are, by most all accounts, nominal at best. So the real question becomes is it worth spending the extra 5 minutes a day to let the car warm up to add a couple a thousand miles to the life of the car? Maybe yes, maybe no it's a judgement call. And if you are running late for work you really aren't thinking about lubrication getting to all parts of the engine and tranny in the the economical and efficient way. You are putting the pedal down and just going, avoiding the 5 0 on your way.
