It's not my fault that you bought shitty phones!
But seriously, I tried Android in 2012, bought a Galaxy Nexus. Hated the whole experience, bought a 920 a year later. Android just wasn't ready yet. It was a disgusting mess and I couldn't understand how anyone could put up with that shit. The phone itself made everything even worse. One of the worst displays I've ever had one a phone. Totally horrendous pentile OLED garbage. 720p, my ass. The incredibly slow storage nearly brought the phone to a halt, as soon as you installed an app. Total and utter gutter trash.
Fast forward two years and it has completely changed for me, when Google unveiled 5.0. Android is beautiful and the Nexus 5 is the longest I've had a phone since I had smartphones (have it for almost two years now!) and if it wasn't for the battery or the overall wear on the device, I'd keep it even longer. I really, really love this phone and at no point could I see myself abandoning it for Windows Phone again. It looks great in red, specs are good, form-factor is perfect for me, it supports wireless charging. If Google and LG hadn't fucked up the 5X so badly, I would've already bought one. Even then, if my 5 breaks tomorrow, the 5X is phone I'd get immediately.
I'm a bit wary of the Galaxy S7, not because of the skin and the problems it might bring, but because I don't want to miss out on timely OS updates and Android N is looking really good.
So good, that Google convinced me they haven't "abandoned" Android quite yet (in the sense that they deemed it "good enough" and 5.1 and 6.0 were really small updates).
And you know me, Van. I'm a super casual phone user and I really don't believe that Android deterioration would be a thing for me. I've updated my N5 from 4.4.2 all the way up to 6.0.1 without a hard-reset and the phone has no issues. It slows down, when I have WhatsApp open for too long, but that's it. So it's not that you're wrong (only in terms of market trends), but your standards don't apply to my non-existent ones and perhaps I'm not the only one.
