Short term parking used to be better. They used to have meters so you could hang out by your car and only pay if an attendant walked up. Now you have to either drive in circles or pay something like $3 an hour. You really do have to drive in circles as security are nazis and won't let you idle for more than 30 seconds.
The TSA security lines are very fast considering the volume of passengers they serve.
Some airlines *cough*united*cough*american*cough* have long lines for check-in, but that's the airline's fault in my opinion. Arrive 1.5-2.0 hours early for any flight and you'll be fine.
Food choices are average. I usually just do Burger King in the C gates as you can refill your soda whenever you want. For D gates I usually do Ruby's Diner.
Long term parking at the remote lot is very affordable ($8 per day) and not all too inconvenient.
Baggage carousels are insanely slow. You'll wait and wait forever for your luggage to arrive.
Free WiFi is very very awesome. Good strength. Free.
