Another "shutdowner" checking in. (Except if I need to do something time-consuming like imaging an entire drive or rendering a really long video, in which case it gets left on after I go to sleep and may finish what it's doing long before I wake up.)

I shutdown and unplug, I live in south-florida and do not need the heat taxing my AC or the connection to the wall during lightning season.
 
BTW...not too long ago there was a flash - bang lightning right over our house and I saw spark between two pieces of metal in my studio....thankfully everything was fine.

Heh. Yeah there's that too. Here in Germany the power is pretty solid - the power lines are all underground, I've had huge storms roll through with nary a blip - but back in Canada once a long time ago we set up to record for a week in an old country house with funky wiring. My friend proudly set up his brand new rig (a pair of linked ADATs, mixer and outboard - this was somewhat before the days when computer-based recording was commonplace) and on the first day we laid down some tracks and were relaxing with dinner and some wine when a serious summer storm came down the pipeline. I encouraged my friend to unplug everything and he said, no man, it's all on power bars with surge circuits and so on, but I said you know, that's a big storm and a lightning spike is not a surge, I really think you'd be better off physically disconnecting from the wall. So he did and literally within 3 minutes we had the closest strike I've ever experienced or hopefully ever will, a shattering, staggering crack so close the air felt buzzy and weird. Half of the electrics in the house were fried - fax machine, microwave, lights - and my friend pretty much wouldn't stop hugging me. Would have been an anticlimactic week if the gear had all gone south on the first night. Instead we did this (hardly anyone's ever heard these tracks!): https://soundcloud.com/ed-roman/sets/the-way-jimi-did-it

Always on 24/7 connected to the interwebs.
 
I maybe have one freeze a year, Since it's my time (no clients, not a studio for hire) I don't get too weird or worried about it. I believe there are ghosts in the machine, but they are "Casper" like ghosts.

I always shut down after my session.

I shutdown the desktop mother ship, but sleep my laptop via the lid. Never with SONAR up though.

My laptop never acts right when put to sleep and reawakened. Like me after a nap, it gets cranky and forgetful. So I always shut it down which will also make it last longer.
