really, windows and osx and linux as is are really to complicated for most people.

we need a linux distro with a simple touch interface.

it would include a program called "money" or "bitcoin"

it would be simple, you boot the computer directly into a screen that has labeled icons for each program. "email" "browse the web" "pictures" "videos"

there would be no automatic prompt for any passwords or anything, it would only cause more problems, since it would be a desktop, theft of the device is unlikely. because of the extreme simplicity, you can lock the machine down to a point where the user will never even notice, creating a very secure machine.

including an online help button, where you push it, and sombody that is paid, can hear them, and see the screen too and control it. each program would have censored parts of the program that the remote desktop can be touched.
