He says one thing that isn't true. He blames Apple for standardizing the concept of not being able to install applications on your "computer" (phone).

This was the case long before Apple, and started at the carrier telco's. Apple was the one who wrestled the control of the app store from the telco's, who were even worse!

Myself and a buddy built cool fun a bartender app (recipes for alcohol drinks) for the Danger Hiptop. It was rejected by the telco (t-mobile) because they were afraid of lawsuits due to the 21+ nature of the app. We never really got a formal rejection notice, they just stopped responding to us. It was also one of those things where you had to build the app first, submit it (to Danger, who then presented it to the telco), take the risk on everything yourself, and then get silently rejected. What a mess.

The problem was the belief we all had that smartphones would mean phones become computers the way we think of them.

In effect fewer people use computers now than used to. They're all online but not empowered the way we had hoped. It's all vice with none of the good parts.
