Everyone's case is different of course, but it's very possible that soon, your wife will be on iPad only.
For large monitors, AirPlay to the TV works great today. I can snap a picture on my iPhone, step inside my house and the next second, show the picture on a 50" TV to all my guests. Instantaneous. I don't have to connect to a computer at all. It even works for videos.
Combine that with a card from Eye-Fi and cloud storage, and I'd say that in two years tops, you'll feel like it's a completely normal and safe way to manipulate your pictures. Use the iPad to arrange them in collections. Show them on the TV. Store them online.
The only thing missing there is editing, if you are trying to do something beyond adding a few filters you are probably going to want either a mouse or something closer to a proper graphics tablet (which is quite different from a capacitive touchscreen).
