well yah if you're someone that doesn't pay close attention to your items then yes a password is great. I'd never pack my iPad in a bag and just hope for the best lol

anytime ur phone locks you have to do it. i'm on my phone daily. i may use it for a minute and lock it and set it down. few minutes later i'm back to it. i'd have to type my password 30+times a day. Your lazy if you can't keep track of your device and it gets lost.
You can adjust the time before the screen locks. I would rather type in my password 30 times a day then be out of luck if it's lost. Laziness has nothing to do with losing a device since it happens to the most diligent of people
