Dave Nicolette gives a great talk called Manager's Introduction to Test-Driven Development in which he explains to non-technical people why software tests matter. You might want to skip the TDD-with-Excel example at the beginning and start with Dave's points about technical debt. Good luck.

I tried to love iPhone gaming. Unfortunately the touchscreen display has many problems when game controls are ported to the iPhone unchanged. You will want to eat babies as you're trying to control your character using a virtual d-pad or the built-in acceleromater. I'm glad touchscreen devices might finally get more games designed specifically for them.
