But for the one that's annoyed me most recently, CD/DVD cases that make it impossible to remove the disc without almost breaking it in half. The technology for that little plastic button that pops it out was mastered long ago, people, you don't need to design yours with mutant fingers in mind just so it looks different.
... and the way DVD cases have those thoughtfully provided finger-holes so you can grab the disc by its edges... which somebody has then gone to the trouble of redesigning so it
looks like they're there but they've been filled in again, so the only way of getting the disc out is to fumble with it and drop it on the floor. Why?
