I've often thought there is opportunity there for building consumer electronics for older people. Every time daylight savings changed, I would go over to my Great Aunt's place and update the clock on her VCR and make sure all her shows were programmed in to record.

I've also seen her insist her TV wont switch on as she impatiently pounds the on/off button again and again, saying, "See, it's not doing anything!"

I wished the remote had a separate on button and off button, so she could pound that on button as often as she liked until the picture showed up on the TV. Idempotent remotes!
