I've got a list of things that I think could be improved.
For instance:
The interface of the remote control? Could be improved for elderly.
The price of a CNC router? Could be cheaper.
The atmosphere of that bar? Could be nicer.
Same here. I want to make a battery powered noise canceling headphone that automatically shuts off if the jack isn't plugged in. Why should a 250 dollar pair of headphones not do this automatically when the battery is required for the experience!?
Because there's a niche market for people like myself that wear noise canceling headphones without music?
Seriously though, if I go in a server room I'm putting noise canceling on. I still need to hear if someone is talking to me, so no music unless I'm doing repetitive work.
Fair enough. I think you are a very small niche though and my proposal would save tens, if not hundreds of thousands of people from wasting expensive batteries. Worth it.
No, not really. I mean, sure, I can think of things that could be cheaper or nicer, but that's almost anything. It'd be easier to make a list of everything that couldn't possibly be improved.

Easy to say, hard to do.
