Thinking about whether or not to get my mom a Surface for Christmas but..

So my dad and I are thinking about getting my mom the Surface RT for Christmas, but she's not exactly the most technology-smart person in the world. She's been complaining about their computer right now (still running Vista!) and I figured this would be perfect for her; the tiles are great, they're big, easy to see/use, and it has everything she'll need; camera for skype, office, email, and internet explorer.

My question is, how easy/hard do you think it will be for someone to use the Surface who has very little tech-experience?
