Linux for my sister?

What criteria would suggest that a naive user could probably make th=
e=20
move to Linux with very little trouble? Here's my guess:

1) Computer use is limited to surfing the net and exchanging email.
2) Someone with minor (?) Linux-savvy is available to do the initial inst=
all,=20
printer, network, browser* and email configurations, and to do an hour or=
two=20
of "hands-on" instruction, and an occasional "hand-holding" via cellular=20
phone (while the user is dialed-in trying to do something).
3) Hands-on instruction would include:
3A) how to turn the machine on,
3B) launch and operate the browser,
3C) launch and operate the email program,
3D) how to make those programs exit (without losing data), and
3E) how to bring the machine down to a poweroff state.
*Note: Cookies on or off? What's safe versus what will the naive user "ne=
ed"=20
for "Microsoft-like" browsing?

     A slightly more sophisticated user might add the requirement for=20
"Microsoft Office tools". That requirement could be answered through=20
OpenOffice with the following criteria.

4) Computer use includes Word and Excel (but not PowerPoint or Access).
5) Someone with OpenOffice**-savvy is available to do some "hands-on" tra=
ining=20
and follow-up "hand-holding" by telephone.
6) Hands-on instruction would include:
6A) how to launch OpenOffice,
6B) how to open existing Word and Excel files,
6C) how to save them as OpenOffice, or Word/Excel files,
6D) how to decide when to save them in one format versus the other, an=
d
6E) how to exit (without losing data) from OpenOffice.
**Note: Fonts seem to be an on-going problem, or is that just me?

     Would those two categories cover the majority of Windows users?
     What have I missed?
