Today 10 years ago I went to Poland to buy a Phone with pre installed #Firefox OS on. The Phone was a Alcatel One, so very shitty. Two years later I installed Firefox OS on my Nexus 5 instead.
It was a very good concept, but sadly rolled out on too shitty hardware so it never caught on.
That's what bugs me about modern phone design, though. They could put Otterbox-type protection right on the phone and that'd be fine for most people. Personally have an S23 and I think it's unnecessarily ugly, thin, and easy to drop, when it's not in a case.
I don't mind it, gives me the choice of whether to put a big bulky case on it. Personally I like it but I understand not wanting to use one.
I also don't mind having the choice of whether or not to use a case, but it might be nice if it were an included accessory.
Samsung has their XCover and Active lines; They're just not flagships.
