"The magic mouse is designed to charge up enough to use while you go and make a coffee"

I don't think I've once remembered to plug my mouse in when going for a coffee.

My coffee is either six minutes and 45 seconds (45 seconds to fill boiler, weigh, grind, wet paper, turn on, 6 minutes to brew) or (does maths) a heck of a lot longer depending on grinder, method, alertness, number of cats.

I don't like the variability of this as a metric.
