Yes, true. But towards the end of your 2 year contract.... the phone's battery would be pretty stale. And the only way to renew it would be to void the warranty/change it yourself with a third-party battery. Or to send it back to BB for them to "refurbish" it, which isn't always an option. A battery even like in the HTC Legend is the best of both world. You get a unibody design, and a replaceable battery!
