Nothing so far. I just like to be prepared for the worst case scenario if I can. But I'm not going to drive costs up 500% to protect from 0.0001% insane user conditions either.

My old scopes are acting up; switches and buttons causing noise on the screen; image is jumping like an old CRT. I'm not going to spend time figuring out if seemingly bad signals are real, or the result of faulty ancient equipment.

I'm waiting for a small scope that had a good review for testing switch debounce. I don't do any advanced scoping routines; I only need it to check 5V lines for noise and switch bounces.
Right now, I just don't know just how sensitive or hardy 5V circuits can really be.

What ordinary household items that a gamer might have on his desk that you would consider as the biggest causes of noise on circuits?

Electric kettle?
Large speaker?
Cell phone playing a movie?

I'm planning on setting up some tests to see just how much noise my circuit can pick up.
