The digital life is 22Gb of photos and videos spanning 13 years so far.
So there isn't a digital life as such, just a pool of electronic memories and information which we share. I couldn't use anything deeper after watching a friend go through the painful process of losing everything tied to an ecosystem of a software vendor.
Oh and I'll only use a system that respects my control for my data. Currently this is windows 8.1 but with the introduction of 10, it appears I'm not going to have to dump that due to the incoming app ecosystem and hit Linux.
If this all looks like a lot of effort, you're only doing the work up front. Retrospectively if you don't do this, you're deferring a world of pain.
