It's pretty much impossible to find an outlet in Germany in public. Certain types of trains have them, but many don't. Like, the only guaranteed outlets I can rely on are at home or at work, and even at work, I'm constantly moving between meetings and simply don't want to futz around with cables all day. I never have to worry about charging my laptop between meetings. That kind of convenience is hard to beat.

Battery life matters. Maybe not to you, but it matters.
