In my opinion, the L5 is a smarter phone than most smartphones. 
Sure, it still needs refining, especially the camera functionality, but it can already do many, many things that Androids and iPhones can’t do (or have not been allowed to do, because it might hurt certain companies’ ad revenue).
I have to politely disagree with you there. Purism’s devs have put a lot of work into making it function on, at least, a basic level, and continue to refine it, as has already been noted.
Yeah, I think they’ve created the expectation, especially for those who haven’t followed along from initial release through today, that all the functionality is advanced and at least on par with conventional smartphones. For the general, uninformed phone-buying public, this is continuing to create disappointment and anger, due to their expectations…and the marketing.
