It's a double edged sword though in that it can discourage users from trying their interface.
Apple's interface shits me because it's all from that one button, and I can never remember how to get to settings because I use that interface so infrequently, so Android feels more natural. Ie. Android has done it's lock-in job, but Apple has done itself a disservice.
(Not entirely fair, I also dislike Apple for all the other same old argument reasons).
Which button do you mean?
