"the only similarity between Android and iPhone is the form factor"

Where form factor includes size, shape, interaction paradigm and user interface conventions, software delivery mechanism, full web browser, on screen keyboard, accelerometer as a key user input device, ... and probably many other things I am forgetting.

If you look at most "smart phones" today, they will be surprisingly similar to the original iPhone (or at least the iPhone version when the App Store appeared).

That's a huge similarity, though. Didn't the original Android plans have a keyboard and look like a Blackberry? And what about the talk about using a stylus with a touchscreen - that talk didn't die until after the iPhone came out.

Android is a copycat, I don't deny that, but it has important differences that make it better than the iPhone in certain cases and viceversa. You can hate iPhone because you can't install apps outside the AppStore for instance and that's not even related to the hardware.

That being said, I don't think that touchscreens should win against keyboard phones, both have certain advantages. A stylus is not necessarily a bad thing either. e.g: drawing, using the phone with gloves on, etc.

There's current Android phones still being announced with keyboards that look like a Blackberry (plus other's with various kinds of slide out keyboards). And the new HTC 7" Android tablet has a stylus.
