The pinch to zoom and scrolling features generally work fine. I did explore the accessibility features and found nothing that addresses my need for easy predictability.
The reason I like the buttons is because I know what they do. And they do it every time.
The reason I hate the gestures is that I'll think I'm doing one thing and get something completely different, often when I needed it to do the right thing five seconds ago.
Clearly, you haven't played with an Android lately. As @[email protected] pointed out, everybody's imitating Apple.
