Last year had to purchase an iPad for one application for work. I've been on iPhone from number one up to five but soon left for Android and have been more or less happy there.

I was utterly shocked at the state of the iPad OS and it's ridiculous unintuitive convoluted and user unfriendly UI. Everything is more difficult, more clicks, more taps, mis taps, mis slides, no consistency, window buttons all over the screen in random places and different on every app and so on.
