Meh I disagree. They are very energy efficient. The OS can be on the ssd and basically be read only making them a bit harder to attack than a laptop that was even just casually in use. You should backup your old laptop channels as much as the pis so there is no difference there either.

I have yet to see anybody running a laptop 24/7 for lightning, while I've heard the recommendation a lot. But I know a lot of pi runners.
