Seriously, you speak like someone who is addressing the issue from a geek perspective. I can't count how many times I've watched co-workers fumbling to find certain settings on their Androids (it's even funnier to watch 2 in particular that have the same phone (either S2's or S3's...forget) but on different carriers so their apps and settings are in different locations. I've used a number of Android devices, my wife's iPhone 4S (including with iOS7), and my webOS phones (bless their little hearts). Android IS complicated and not the best thought out or organized OS, not by a long shot. Once you know it, it may not seem complicated, but it is.
As for satisfaction, I can Bing it and find numerous examples. Here's 3 from different time periods and methods (JD Powers is by phone, but you can get the gist of it):
First, second, and
third link. There are more, but the trend hasn't changed. Android has frequently had one of the higher ratings for "likely to change OS" when surveyed for the likelihood of someone changing from the OS they are currently running. The vast majority of smartphone users want 1: social networks, 2: email, 3: browsing, 4: messaging, and 5: casual games. WP8 has all of that and is probably the best at most of them. Casual games is really the only "weak" spot, but I have over 40 games on my Icon, and there are a great many more. They don't always have the latest and greatest, but most of the popular ones are there.
I stand on what I said. I haven't been limited on my Icon at all, and I love the phone, much more than my 822.
