Was going through the specs and found this interesting tidbit. HTC U11 supports Flex Storage which is nothing but the adoptable storage. You can finally put your SD card to good use then
Not sure if I would recommend anyone to do it though. Even the more expensive MicroSD cards still have a much higher error rate than internal storage.
What I like is that they followed Samsung and shipped it with at least 64GB internal storage. 32GB should be a no-go in 2017 (I'm looking at you LG!). Personally I wish more OEMS would follow Apple and offer more internal storage options. Samsung tried it with the S6 but sadly stopped it later.
