> Others have said that if Jobs were still alive, AR would be ubiquitous by now, and everyone would have a stylish pair of Apple glasses. I think that is exactly right.
I don't think this is true. If anything, we'd have ipads with no stylus. Steve Jobs was a visionary, but most importantly a good business man. It's not like everything that made the iPhone was in house and strictly an Apple invention. Apple was lucky in that it bought a company that had developed the multi-touch technology the phone so heavily relied on. Without that, the iPhone wasn't going to happen when it did.
Additionally, a lot was sacrificed to make the iPhone happen. People took some serious physical and mental tolls in order to help ship that product. Marriages crumbled. The pressure was ruthless.
