I've got a few running here and there (whether they like it or not), but there's nothing wrong with just running it on a computer you have on most of the time . People differ over this. But if you use it to broad cast transactions, so long as your prvkey hygene is good, you dont need to use a special device to run a node in my opinion. There's nothing wrong with just taking an old laptop and running electrs and bitcoincore on it so long as you keep your keys off the computer
