Different people care about different things :) I also think about snapshots differently. For me snapshot is actual copy stored on a different hard drive or other medium. So copy operation is never going to be instant. Scenario in the article is power loss so that is also not something I worry about that much. Mostly I worry about hardware failure where I would not be able to turn on my laptop/server again. For power loss UPS or battery in laptop is my go to solution.
