I know I am! ( ^ _ ^ ) I'm surprised that my car doesn't have a bazillion dents in it by now! : ) Go Honda!
I don't know advantage, but ADT suffers from bigness. If you are talking about having a system installed, I have no advice. If you are considering monitoring an existing system, I suggest you try for being allowed to cancel service at your will and at any time. You should specify that a monitoring device (often a DACT) will belong to you. Then any monitoring company could take over that task. If you are considering a fire alarm system, talk to your fire department for advice on what to specify. If you are talking of an intrusion system you will probably have a hard time getting good advice.
You don't want to put anything permanent on the bottom as it will prevent access to the compartments there. ~ Also, heat will build up if you put something that covers the bottom.. Heat is a major killer of laptops. Putting them on a bed or sofa can increase heat buildup if they are running.
