This is all great to know. I had a Sony Xperia that I fiddled with sailfish OS on for a while but again, it never fit as a daily driver.
Thanks, that gives me an idea for my two Xperias, one of which just retired yesterday.
I'll have a look at the 6 and 6t. Currently I'm running a Fairphone 5 with Android, so not ideal, but the hardware is great and I absolutely love the company's dedication to longevity of hw and sw.
Warning: the TechRadar review repeatedly called the 6 a midrange phone, and I'd say it's clunkier than my 2-year-old (and $300 cheaper) Xperia. I'm still looking for information on the Clove warranty I saw mentioned somewhere since Fairphone won't warranty phones in Canada (and I'm not optimistic about Clove). The postmarketOS wiki says that althouhg the 5 is among its best-supported, the 6 boots, but not much else so far.
On the bright side, the postmarketOS developer who's working on the port in his spare time is employed by Fairphone by day, and has a YouTube channel.
