I was a Kirk man myself up until I got the phone that I have now. By which I mean, I always had a classic thickish flip phone. I didn't really think that any of the other features were necessary.
Now I've got a touch screen Android, which is pretty slick. It's easier to type on (I mostly communicate through text messages), and the camera is of course better because it is a newer model. And I suppose that the touch screen does make it easier to navigate. I don't often use much of the other special features, though they are nice. Having this phone hasn't really made me oppose flip phones, though, but perhaps I am nostalgic and would just like to see people continue to carry them around if they so please.
