I had an epiphany today and I'd like to share it. The biggest advantage iphones have is their touchscreen. So why not combine the best of both platforms. A physical keyboard and instead of a trackball or trackpad the interface is through the screen. I even have the perfect name: Black-i. You're welcome.
Problem #1 is size, that's gonna be a big phone unless you keep the screen small like a Curve or Bold and just make that the touch screen.
Second, I would argue that a touch screen is not an advantage. I hate them and so do the majority of people with phones that I know. For us the advantage is a non touch screen interface.
