Limitless paper for a paperless world

I've been at this for almost two and a half years now, and I came to a realization just today: who uses "legal" size paper anymore? I can't remember the last time I encountered the ol' 8 1/2x14 at school, and I only saw it at work in old leases.

If a notoriously tradition-bound profession like the law can get rid of a bizarre and annoying standard from everyone else's, surely the most dynamic country on earth could adopt the metric system.
