I've seen this posted a few times so I'll try to address what I can.
Hopefully this will help some of your problems!
Thank you. I am sure there are things that I missed, and I don't claim to be an expert based on 3 week usage. What's most important to me is, while it doesn't always work out of the box with the iPhone, it does most of the time, definitely more often than the SGS 2 that I had.
As far as the backup solution of Android, thank for the information. However, the fact that only some of the apps are backup, and user need to manage and keep track what are backup and what aren't is still a big fat failure in my opinion.
