“It's done in hardware so it's cheap” (2012)
This is one of these things that look very obvious to me, to the point where it seems not worth discussing. However, I've heard the idea that "hardware magically makes things cheap" from several PhDs over the years. So apparently, if you aren't into hardware, it's not obvious at all.

Why Does My Remote Control Need to Know My Location?
Here's an interesting user-hostile pattern which could easily be avoided if programmers and business-people thought like regular humans. I have a Pioneer / Onkyo sound system. It's pretty nice and comes with a (not too crappy) Android app to let me remote control it. One day, the app updated itself. The changelog was…
