In conjunction with the release of the rugged Rugby from Samsung, AT&T's celebrating its good fortunes by dropping pricing of its push-to-talk option from $10 to $5 (a 50 percent cut, for the mathematically challenged). That puts its rate in line with Verizon's, while Sprint stays the lone ranger up in the clouds at $10 a month. So, you know, if your conundrum comes down to Rugby versus Boulder -- just make sure monthly PTT pricing doesn't come into play in your decision.

Update:
Sprint points out to us that most of their plans actually include Direct Connect bundled in with the pricing. The simply-named "Talk" plans do not, and a $10 bump beyond those bring you to the "Talk/Message/Direct Connect" plans which, as their names imply, include both unlimited messaging and PTT.
