Linux for my sister?

>      What criteria would suggest that a naive user could probably make the
> 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 install,
> printer, network, browser* and email configurations, and to do an hour or two
> of "hands-on" instruction, and an occasional "hand-holding" via cellular
> 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 "need"

>      A slightly more sophisticated user might add the requirement for
> "Microsoft Office tools". That requirement could be answered through
> 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" training
> 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, and
>    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?
