I was going to write exactly that. Sony has virtually cornered below-5-inches market segment. I loved my Z3 compact until its touchscreen failed after 3 years of use. I've just upgraded to XZ1 compact and keep loving the device. It's a perfect form factor for me, screen estate is enough and being just 720x1280 pixels it saves power. All phone's specs are decent, it has a great GPS, is fast, etc. I've searched high and low for another phone below 5 inches, but there are almost none. It would be bad luck if Sony got out of smartphone business :( On the other hand, XZ2 compact tries to cram 5-inch screen into previous dimensions and it makes it thiiick. So maybe they get lost, too. Which is sad. I guess I will have to buy 1 or 2 spare XZ1s ;)
