Another benefit: Don't need to be here every day. Can burn through that mana in one or two days of casual use, then feel free to take some time away, while it charges. Far more consumer friendly. And better for one's health.
Though I have doubts I'll be sticking around much longer, it's been good to see and experience this change. I see it as a good thing. But in general I think majority will apply it to old habits, the new generation will follow suit and the benefits will be replaced with tradition.
Looking forward to being wrong about that.
