> you would be there all day before someone said "I wish I could replace the battery"

Before that, you wrote "One of the most frustrating things about HN is that people seem so unaware of how idiosyncratic their preferences are" and it's exactly what I could say here. Not everyone has lots of money and for some people extending the life of their phones is important. They really do wish they could replace the battery without hassle and without paying a shop to do it.
