I thought this was Hackernews and people fixed tech inconveniences with random scripts! I’m sure someone on here could hack together something to check for updates and run the update or automate that process with a click from your phone.
I agree, but sadly it's getting harder and harder to do that sort of thing. It seems that almost inevitably, along with those fancy framework abstractions come tighter restrictions on how much the user is allowed to do things which are not explicitly supported by the UI. All in the name of "security", of course.
With the PS if I leave it alone and powered on it will take care of itself. But I turn it off so it does not use as much power. I have enough other items in my house turned on to heat it up :)
