I can definitely see how that is the best of both worlds. In fact, I thought of doing that before I bought an iPhone, but carrying around fewer devices is more important to me than having a perfect keyboard.
Also, being able to listen to music (with a standard 3.5mm headphone jack, btw) and not worry that I'm missing calls is invaluable (the call just interrupts the music).
