Maps and Email is better example to use, but the point is that by not letting you change you aren't advancing the OS, but that's not true at all
All separate issues. Both Android and iOS are constantly changing and improving. Both OSes are great choices for consumers with flagship phones on each platform.
The pissing contest is silly. People can have their preference - but that doesn't make the alternative "crap." People should just enjoy the phone they have and the experience they've chosen and/or switch when they no longer are.
