> why don't coffee machines that can start on a timer have a backup battery for their clock?
As a European the thought wouldn't have come to me. Brownouts just don't happen (see this 0.5% frequency dip making headlines), and a blackout is a once-a-decade event for any given house (probably even less frequent than that).
So your answer is probably that demand for that feature is far from universal, and a coffee machine is much lower stakes than for example an alarm clock.
> Depends. I'm in a rural area, and I get 5-second power cuts every couple of months. It's the main reason I have a UPS under my computer desk.
This. Can't put the coffee maker on an UPS though. Or not on a cost effective UPS.

Actually for the alarm clock i'm just going to be late. Not having coffee hurts much more!
