This would also certainly lower the bank administrative fees that I always have to pay in advance to my Nigerian business partners!

I think you should avoid explaining tech stuff as to an 80+ years old grandpa as much as possible. Perceived complexity is exactly why a lot of senior people won't even touch a computer with a pole stick. I've been recently confronted to the similar problem as the author: give the simplest computer to my grandpa, and teach him how to use it. He already tried using Windows and Mac, but gave up because it was too complicated for him. I hope my experience will help you somehow. First, you have to ask yourself the right questions:

- What exactly does he want to do on his computer?
- What is the best and easiest way to present these functionalities on his screen?
- What time do I have?
And *then only* you can ask yourself what software/hardware you'll use, depending on the answers of the two above questions.
I customized a Xandros EeePC 900 to be even simpler to use than with stock setting. Here's what I personalized:

- Five functionalities: Internet, Email, Writer, Solitaire, Skype. That's five huge buttons on the main screen (no other buttons, there's alt+t terminal for administration)
- Kiosk mode Firefox: fullscreen, back button, home button, print button, font size up/down buttons, close button (and Adblock plus installed)
- Netvibes homepage with local news, weather, wikipedia search, and video search. (no Google, too exotic for my grandpa).
- Disabled reminders, unnecessary tooltips, auto-updates, etc.
- Removed all the unnecessary buttons from OpenOffice, Firefox, Thunderbird, Skype.
- Removed the taskbar, and the maximize/minimize buttons from windows (basically: removed apparent multitasking).
- Configured the power button to be instant on/off (no confirmation screen etc).
- Configured Thunderbird with his email address, ready to be used.

Then comes the teaching part. In my free time I made him a little manual with a lot of screenshots, and spent two hours with him explaining him what he wanted to know, and I used a tutorial approach.

The only downside of my experience is the great amount of time required to customize Xandros and to write the manual, so your solution might might be different depending on the time you have on your hands.
But my grandpa seems to be satisfied with the result. It has been six months since he touched his EeePC for the first time. He uses it everyday now, and never had a crash/problem (yet).

There are two problems with those Google pictures: - There are more people who can see you on the internet than in the street - The picture remains available Now take the exemple of the man who appeared on a picture walking out of a strip club with his face recognizable in hi-def. A bit embarrassing.
