Okay, you won't impress anyone by busting the Centro out mid-meeting, but then this smartphone didn't sell more than a million units to date because of its looks. It's become 2008's sleeper hit thanks to a beginner-friendly price point and feature range. So while the camera's lousy and the body looks geeky, you'd be hard pressed to find a cheaper and easier way to send emails, IM your friends, and, yes, even make calls. Think of it as a gateway drug for aspiring CrackBerry addicts.
