[RndTbl] Linux "mom ready"?

Faced with an expiring XP, I had a thought about moving my mother (complete techno-luddite) to Linux. She only needs an office suite (OOo instead of Word should do), Skype (works fine on linux, and her webcam is supported), an email app (evolution/thunderbird instead of Outlook), and that's about it. It's Linux or Win7. If I'm setting up and admin'ing, are there any downsides really? I can make it look/behave much like XP, so the learning curve may be smaller than with Win7. Am I delusional because I breathe Linux? Or can this be done? Corollary: What distro?
