I don't want to have to log into my alarm clock anymore.
"Ditch Windows" is a fair answer. I'm working on it.
I haven't encountered this luckily. The only use case I can imagine is syncing alarms and timers across devices? But...I use timers for working, and alarms for waking up. I don't really want those to sync across devices. And it doesn't really seem worth a backup - it takes 30 seconds to set a new alarm.
