I seriously love my x performance. Had since it came out not one problem. Had the z3c before and used until battery stopped holding a charge. Only thing stopping me from up grading to the xz premium is the size. If next sony phone doesn't shrink bezels I'll move on.
Good news for Sony. If their purported XZ1 Compact delivers, I'm planning to be one of those 16.5 million people.
If they would just improve image processing, combine ois with eis, use better speakers, and be more globally available with improved advertising their sales would probably soar!
