I spend a good amount of time doing support. I still play around with plugins, tools, and interfaces, but I try really hard to stick with defaults. One thing I do often do is remap Caps Lock to CTRL and it surprised me how often this catches people (and drives me nuts when I'm using their computer).

I have a Logitech Harmony 700 (a very mainstream universal remote), I don't care for it but it's the best I could find, because I use a receiver and Apple TV. Whenever I have guests it's always a mystery for them how to use it.
