I can't speak for anyone else, but I have been an Xperia compact phone user going back to Z1 Compact on KitKat, (2014 I think - I actually had an X10 Mini in 2011 and an Active in 2012, but things were different then...), so I am always monitoring and occasionally testing whatever they come up with next, and, when I started to get interested in the XZ phones, what I noticed was that the specs for XZ1c and XZ2c were almost the same, but the XZ1c seemed harder to get and more expensive. I have no idea why, beyond speculation, but that's the main reason I never bothered with the XZ1c, (but am currently using my second XZ2c).... Maybe Sailfish devs noticed the same thing...
