The number of people that have it on surprises me.
I'm reminded of the 24 hour news channels who love to put ultra detailed timing. If there is a press conference at 9pm they don't just say it's at 9pm, at noon they'll start a 9 hour countdown.
So if you watch the news at any point that day you'll know it's 8:43:22 until the press conference. It's 6:12:43 until the press conference. It's 5:24:46 until the press conference.
Those numbers don't mean anything.
When I started writing this comment I had 92% battery left. Now I have 91% battery left. If I ramble for too long what if it goes to 90%? At the rate it's dropping am I going to have less than two hours of battery life left? Where is my charger?!?!
Or, I can just look at the list mostly full icon. I'm good.
