Nice hardware on an ancient platform
I've been an Apple fanboy since the iPhone2, then 3, 5, and 7. My previous phone was (cough) Windows based.
Let me tell you, the 3D touch on the iPhone7 was more than a marketing catchphrase. It was a marvelous piece of hardware. But, I took a photograph with the phone's camera and was shocked at the horrible distortion. It's known as the "watercolor painting effect" - apparently a sharpening filter gone amok.
Then, I purchased headphone dongles to compensate for the lack of a 3.5mm jack. The bluetooth headsets had low volume. There is no way to expand the memory. The whole environment is ancient and full of quirks and bugs. Less than 1/2 way into paying off the phone I sold it and purchased the Galaxy.
What locks people in, by design, are the DRM laced iTunes, Apple app store only apps, and lightning connector accessories. Rather than innovating and improving they resort to licensing and patenting to make it annoying to switch. The factory radio in my car refused to work with Apple for hands-free anything. then, they removed the fingerprint reader which they introduced just a short while ago.
Samsung and Google and Android have their own issues - but, I find it refreshing to deal with them compared to iPhone7 and beyond.
I still have my iPhone5 as a media player. It has a headphone jack.
