Lumia 550

Nothing, it's just a boring OS. It's like a cross between iOS and Android, with the best UI out of both of them by far, even in user designed apps. I still prefer my podcasting and uhh Sup Forums app to the ones I have to use on Android now. Battery life was far better too. Only real app I'm missing is Snapchat when I'm on Windows Phone. And flavor of the month apps like Pokemon Go, we don't get those, and give us your money startup apps either.

If I didn't save $10-15/month on my cellphone contract, I would still be using my Windows Phone. Sometimes I still do. Cortana is just as good, and works with Windows 10 well too.

Oh the SSH apps suck donkey dick too. But, they somewhat work. DESU, there isn't an SSH app for UWP that works well either, else I'd be using that.

Once more devs realize the can hit the entirety of Xbox, Win10 PC, and Win10 mobile with their shitty apps, there might be more edgecase apps made, as well as flavor of the month ones.
