Is the computer is dead? If not dead, than it definitely has a terminal disease (pun intended, get it?) Everything is a computer, but the only true thing that the normal Jane sees as a computer is her laptop or desktop. How soon before the laptop is obsolete? You already can do almost anything that you do on your laptop with your cell phone or your ipod or your tivo or your xbox.
My bold prediction - in 10 years we will no longer be using "computers"; we will be using other devices with other names that have an operating system, does searches, entertains us, is mobile and is connected to the internet. Heck, we already are.
