My OH had a Nokia C301 too. I moved her to an iPhone but that was because she has an iPad. There are cheaper and as good alternatives available. If he's not interested in a decent camera then have a look at the Moto G. However once he discovers what a smartphone can do he may well want to load more apps and have a decent camera built in. Suggest that you call in at a local store nad both of you have a play.
