[plug] How to convert without having to support??

[Paul Antoine]

Folks,

In deference to everyone's desire for on-topic content, I proffer the 
following conundrum:

I have been approached by an acquaintance who wishes to connect to the 
Internet for the first time.  He's 60+ year old pensioner and 
computer-illiterate, though his kids/grandkids are not of course.  He's 
also cheap... and wants a computer for $300.

No problem I thought.  I have lots of old PIII bits lying around which 
will happily run Ubuntu, and another friend of his has donated a screen, 
keyboard and mouse.

I want him to run Ubuntu so he doesn't have to buy an M$ license for XP 
(Win98 is now no longer supported with fixes) and to help him avoid the 
worries of malware, spyware and viruses.

Now here's the rub: I don't want to have to teach/support him as I 
simply don't have the time.  I'd like his kids/grandkids to be able to 
do that for him, but am afraid that their unfamiliarity with Ubuntu will 
make them ineffective in that regards.

Ideas? Suggestions?  I await your collective wisdom...
