Engadget - Ladies and gentlemen, welcome to the world of email. Yes, email! Sure, many of you have given up on the stuff in favor of more instant means of communication, but don't worry, because that's here too! Yes, the BlackBerry PlayBook, which was released 10 months ago, is now finally able to send messages all by itself. Sure, BlackBerry Bridge is still there and more useful than ever, tying the PlayBook even closer to your work-issued smartphone, but the 7-inch slate finally feels like it can stand a little more solidly on its own two feet.
