I know this has been talked about and wished for a dozen times over but I really want a Sony Xperia Z4 (or Z3) with the Windows Phone OS. I dropped by a Best Buy today and got to look at and handle a Z3 and it's a really nicely built phone. It's thin and yet feels durable. I own and use a Lumia 1520 and it's a beautiful handset, but the Sony Xperia is beautiful yet also has a rugged feel to it. Here's to forever dreaming about Sony coming to their senses and/or Microsoft coming to their senses to put a Windows Phone OS onto a Sony device.
