At first blush there's a lot to like about BB10, BlackBerry (née RIM)'s last great hope at redemption. But the first thing you might love is the revamped BBM. It's crazy slick, and your iPhone is jealous.
What can you do with the new BBM? Reliable messaging, for one, which alone gives it a hand up on iOS. But it's also got some gorgeous video chat, and a screen-sharing feature that lets you share whatever is on your mobile desktop with someone halfway around the world.
