I can't believe people are still complaining about this stuff. Anybody who's used an iPhone for more than a day can figure out all the interactions on this screen just by looking at it. Others can tap around a little bit and should be able to figure everything out in 5 seconds. We're way past the point where we should be designing for the least technically-savvy of our users.
Other examples listed later in the post - that buttons don't react immediately to user interaction, that pickers are finicky, etc - are legitimate concerns that Apple needs to address. But they are a separate issue from the aesthetic direction that Apple has been pushing since iOS 7.
