I have a HTC One (personal) and iPhone 5 (work). Lets just say I love my HTC and hate the iphone.
My main issue is the lack of customisation / widgets on the iphone. Everything just seems locked down in comparison.
The HTC is perfect for me. Its great to hold, the screen is stunning, its unbelievably fast, scrolling through websites or emails is very smooth, etc etc.
I also like that a lot of the top paid apps on iPhone are free on Android.
My previous phone was a S2 and GF has the S4. Ok phones but appeals more for younger kids as everything is soft, rounded and colorful (ie not very sharp). Hope that makes sense…?
