If you think the idea is the easy part, I question anything else that you might say.

Also, ideas are evolutionary. Go watch Steve Jobs' D8 interview. See how the iPhone didn't start as a phone, and then tell me Jobs doesn't deserve as much credit as he does.

Remember that this isn't about the iPhone as a device, but the device as an industry mindset changer. An idea goes beyond just the idea, and Jobs dared to envision and execute a strategy that put the phone before the carrier. If what Jobs did isn't that great, then why didn't anyone else do it?
