If you could have two devices...

So I've just been offered some new phones from work to help with my job. It revolves around application testing etc.

I already have a S4, Note 2, iPhone 4s, iPhone 5c, iPhone 5s.

If you could have any two devices, ideally not the above, what would they be? I'm really interested in expanding my access to Android and Windows Phone devices.

They must be already released, or due to be released before June!
