This was Apple's first attempt at cell phones. Other manus were integrating music in to their own cell phones. If Apple failed, the others would slowly eat away at the iPod. If Apple failed, there would be no iPad. There would be no Apple.
Oh gosh, Google guy. Apple took a big risk w/ releasing the iPhone. Google just followed the leader with minimal risk (relatively speaking). There was nothing like iOS on the market with a software keyboard.
