It's also to light off the catalytic converter and to get the oxygen sensors warm enough to be able to read the oxygen stream.

Short trips hurt no matter what, though a block heater would help immensely. Nope, there's nothing wrong with your car.

I wish I had such a low cold idle. I'm at 1500-1800rpm at first start, and it'll gradually taper off until normal operating temperature. At 120*F coolant temp, mine is still idling at a full 1300rpm, and even at 165*F I'm still at around 1000. Get over 180, and it finally falls to its ambient 800rpm (~650 in D).
