That’s interesting @jesse, thanks.
I always ensure the magnet is secured before connecting to a computer. When I disconnect I always unplug from the computer first.
Everything is still fine after over a year travelling back and forth to work with the keyboard.
I’ve never had any problems with charging a phone (except for dust collecting in the charging port), so maybe my wear and tear worries are unwarranted. Collection of dust is unlikely. In that case, the only benefit is the convenience.
