Relatively speaking those parents of mine are to pop their clogs one day (well, Burkenstock sandals, one day being many years hence). I would not be happy about deleting everything on their PC's, I would want stuff kept.
However...
With my own 'digital life' I would prefer people to just fdisk/powerwash my PC-style devices and send the things to the charity shop. There really would be nothing to see on any of my machines, the cloud can just be forgotten, nothing really matters. I don't know if others would see it that way though. My point being that 'what you would do' concerning your oh-so-precious online life is different to what you might think when it comes to someone else's digital life.
