Evaluation of Prototype after 3 months use

I've had the parking spot recaller prototype attached to my keychain for 3 months now.  Battery is still doing fine. The buttons were broken by a women with sharp fingernails.  The buttons have to be pressed by the pads of your fingertips or the metal dome can get bent.  I looked into some other way of doing the buttons but all other options seem like they would complicate things too much.

Software Improvements:
- Have the unit shut itself off after 2 minutes even if a button is always being pressed.
- Improve button debounce algorithm.

Design changes from here we are planning on creating a new model using all through-hole components.  The Through-hole version will allow us to make a board that is single-sided and make the assembly process quicker.
