Wife offered new work phone choice

Right, so we are an iPhone family. I have an iPhone 5 and my wife has a iPhone 4 (not 4S).

Wife currently has a BlackBerry for work. They are about to replace the BB and have offered her the choice of the following:

Samsung S3 / S4 16GB

Samsung Note 2 16GB

iPhone 5 16GB

I'm tempted to tell her to get on of the Samsung's so that I can play with Android. Then again, she doesn't like change and she's jealous of my iphone 5 so maybe it';s best to stick to Apple.

What do you reckon?
