Maybe This Is Why The USGA Doesn't Mind On-Course Electronic Device Use

...@ $3.99 a pop, I smell a major new revenue source: the mobile phone Rules of Golf app.

I can't wait until a player whips out his iPhone to consult the rule book, or uses it to take a photo of mud on his ball. Or maybe they could do both, and email their rules question in from the phone? That ought to speed up play.
