Why does the fact that the input mechanism is a finger instead of a mouse affect installation of applications, installing security updates, and updating drivers?

These are two completely independent factors.

There is nothing magical about a touch screen that instantly removes all the complexity in an operating system: you're drawing false correlations. "This tablet X is easier to install applications on than this computer Y. Therefore, touch interfaces make installing applications easier."

I didn't imply at all that it was the touchscreen that makes tablets easier. I thought by the examples I gave that it was clear I was talking about the simplified paradigm of a typical tablet--a centralized store to purchase, install, and update apps; a fullscreen, one-app-at-a-time interface; no antivirus, antispyware, defraggers, registry cleaners, and so on; and a highly mobile hardware device that comfortably rests in your lap and requires no hookup or peripherals to run.
