That is, until two weeks ago when I got my new iPhone. I had to, the old one couldnt upgrade to the newest iOS.
I feel ashamed to admit, that I had one or two days of extreme frustration just learning to do basic stuff. It was not about the shape of icons, but more along the lines of what you write. Swiping patterns, button press sequences, and the time you should hold down a button. It is ridiculous.
Some of the blame is on me for not being mobile phone savvy, but it is indisputable that the UX has deterioted significantly. I suspect it will just get worse going forward.
