My inbox is not an imperative to act -- only the unread bold items are such an imperative. Those are to be replied, forwarded, flagged, deleted, or ignored. If it's read then I've done one of those actions. No need to archive off the inbox to get that discipline. All the tools are there.

I found that it's a disadvantage to not have the stream of activity that Inbox infinity provides. All incoming email is sorted by date so I can always see my activity.
