My take on this is that these are the reasons why things like the iPad will succeed, namely locked down single purpose devices that do one thing at a time well. Essentially Internet based appliances.

They will succeed primarily as some people (evidenced by this article) only use the Internet to do a few specific things and don't know of, or don't want to know of the specifics (address bar, search bar, certificates, etc) of using the internet in general. Therefore they will have their device with the icons of the things they use on the home screen, and not really venture into using a browser at all, just use the specific applications. Thus no more worrying about how to access Facebook or navigating a browser properly, they'll just click (tap) the Facebook icon and they are there.
