I use the physical authenticator just because it seems like it takes less time than it does to unlock my phone and launch an app... ? It's become habit to leave my keys at my computer desk ready to be used (if they're not in my pocket). So it's one button press away. If I think "I'm going to play WoW" the first thing I do is make sure I have my keys. It's instinctual at this point.
But if it's taking any time at all to decide, protect your account right now with the mobile authenticator. It's free.
Then think about getting the physical one.
