Yeah! And I bought a phone to be a phone! I didn't buy a phone to be a camera or messaging device or Internet browser or to game on the go or to be a gps or to check my email or to video chat. I have a point&shoot, 2-way pager, computer, Gameboy, Garmin, laptop, and a Logitech camera for all that!
The point is, there's no downside to having the option, assuming it's done correctly and Apple-esque. Why only buy a MacBook Air when you can get an iPad with your purchase? Why only get an iPad when you can also get a MacBook Air with your purchase? If you could buy the two parts separately, what's the big deal?
I think people who are opposed to this don't have both devices. Seriously, there's no reason why this couldn't and shouldn't be done (from a consumer perspective, at least). It would be completely and utterly awesome.
