See, why I prefer mine is; storage is (effectively) free, focused attention is not.

Inbox Zero requires you to seriously think and evaluate every single email, but my way allows me to subconsciously triage.

And I just realized why it's so effective and feels so effortless -- it uses a mental mechanism that we all must use everyday, unfortunately; it's the same filter that lets us ignore advertising (e.g. billboards), which we've all had to practice anyway.
