I would look around and see the game options that best suit your wife. I would think that Wii or XBox may be a better fit than the PS3.
Personally, I have two PS3's and a Wii....the Wii is great for exercise games and kids games and the PS3 is great for Call of Duty, Battlefield 3 and Blu-Rays

I already have a Wii, and while it's fun, my wife wants something we can use for Netflix too. I've tried connecting it to my wireless, but the connection sucks, so we're planning on getting something new, and leaving the Wii in the basement for our daughters to use.
The biggest reason we looked at XBox was because of Kinect - but I'm not a fan of having to pay a monthly fee for XBox Live (versus PSN which is free). I also like the idea of having another Blu-Ray player in the house.
