Yep. I had an XR. I kept it until the battery started dying. Now I have a 13, which I got refurbished when the 15 came out so it was not all that expensive. I'll keep that until the battery starts dying and do it again.
And really, the only reason I'm sticking with it at this point is that I'd probably have to spend several hundred dollars to replace all the paid apps and games I have. If there were some way I could just transfer all of them to an Android, I'd probably get one.
