Has anyone here ever tried using nitrogen for the tires?

No kids! Nitrogen is lighter than air... pay it! It'll make your car go faster! Cuz its lighter!
Hahahha I'm soooo going to get this one.

Nitrogen is used in tyres becuase it expands and contracts LESS than regular air. It still expands, just not as much. This is mainly due to the fact that there is much less moisture content in Nitrogen than air, but there are other reasons as well that i won't go into becuase they are trivial.
Nitrogen is pointless for road use. It is used in racing cars and aircraft.
In racing cars, the "cold" pressure is almost irrelevant and tyre pressures are determined based on what they will increase to when they are hot. For instance, you might want your tyres to be 30psi when hot, so you may set them at 25psi when they are cold. The friction of the rubber on the road and the flexing of the side wall (and radiant heat from the brakes) will increase the temp of the air in the tyres, thus increasing the pressure. For the first few laps (or until the tyres are up to temp / pressure) the car will not handle as well due to reduced tyre pressure.
Nitrogen is used, becuase it means you can set the "cold" pressure higher for example 27psi in the above case. This means that for the first few laps you may have an advantage over a competitor who is using just air.
It should be noted that the higher the moisture content (humidity) of the air in the tyres, the greater the difference between hot and cold pressures. Using "dry" air will give almost the same performance of nitrogen. You can buy an air "dryer" which hooks up to your home compresser which heats, then cools the air and extracts most of the moisture out of it. Example: http://www.pacificaircompressors.com/pdr515.htm

I agree with Furious_G. I had Nitrogen in my tyres for two years. All that talk about increased gas mileage, less wear n tear is total nonsense. The only noticeable difference was the green caps you get to cover your air inlets with.
Not worth it, don't do it.....

not worth the 75 bucks dealers wanna charge
not worth it at all.
in HK I pay $25 which is very good for the money. and unlimited refill until you sell the wheels.
any thing over $30 is not worth it
