Rankings of wait cursors by annoyance:
5: the windows hourglass
Whatever is going on is an older process it can’t really take that long…right?
4: the iOS spiny gear wheel thing
Usually just means mail is downloading more spam but it occasionally occurs by itself, usually when you need to make a phone call
3: the windows donut
Cons: can last minutes to days depending on what just happened. Isn’t an actual donut
Pro: looks like a donut, usually gives you time to go get a donut
