A lot of things. For example you can use it to copy files (moovies, music, etc) on the drive of the console to watch them. Or you can download data from the console itself (screenshots, video recordings, etc). You can use SSH to run commands to automatize things, for example turning off the console, launching an update, installing new software, etc, while not being in front of the TV. Finally you can use it to diagnose problems on the console, for example you can connect to run a diagnosis, from which you may find out that the hard drive is causing problems and you should replace it, or the console is overheating and thermal throttling, etc.
