I was using a Fitbit force for about a year and a half. I found the steps and stair tracking motivating. I then got Fitbits for my parents and my mother in law, who now view each others' steps and can compete with each other even though we're on different continents and speak different languages, which is fun for them. I'll probably get a charge hr or a surge to upgrade soon.

I think that social aspect is really valuable for motivation, so it's worth taking into consideration whether or not your wife has friends who use Fitbit.
