> all that hard problems (backups, updates, ease of use, experience homogenity, etc.) are solved

This is a bit funny to me. I'll give you the homogeneity argument, but as for the rest, as someone who has owned both iPhone and Android since 2008 or so, it took Apple a long, long time to catch up to Android in the backup/update department. Remember having to do everything via iTunes? I remember.

Now, they're essentially the same in that regard.
