I have to say I"m a big fan of the intelligent access and push button start. Not only that but the Titanium comes with remote starter as well. You can set it to start defrosting the windows during the winter or turn on the AC during summer.
Plus, I got two daughters and everytime I stop to get the mail I feel like one of them is going to jump in the drivers seat and take off. With the key being in my pocket - I don't have to worry about that happening!
Also, there is something pretty sweet about the MyKey thing as well. You can create a MyKey that limits the car top speed, radio noise, seat belt indicators, and more features so if you kid starts driving you can see exactly how many they have driven.
