I had used iPhones since the 1st one, upgrading to every one (except the 3GS), after having an iPhone 5 for a month I finally bit the bullet and bought a Nexus 4, it was "different" for maybe 3 days. The trick was to approach it with a fresh mind, not try to do everything like you did on your iPhone and get frustrated when things aren't in the same place.
Yep, I switched to the GS1, man, that was a bad move, and little did I know the last person had rooted and installed an unstable update. -.- So it was frigging laggy, so I fixed the ROM issue and sold it, for a Nexus S. Man, that was almost as frustating as the jump from iOS to Android, they really overhauled android back then, and still do!

Wow, my 6 year old navigates my wife's Galaxy Note 1 with no problems. He also has no problems with the iPads. He's not allowed to touch my GS3.
HAHAHA Yep, I never understood why he couldn't. Since then he has "seen the light" and switched the HTC ONE, he takes a bit to get used to it, but is quite good with it now. I guess young people are like sponges, soak up everything, plus your son is probably pretty smart. I know I wouldn't have been able to at six, well, they didn't exist. *facepalm to stupid comment*
There are enough differences between iOS and Android that switching from one to another can lead to some confusion. As an Android user, I find using an iPhone to be confusing and annoying at times as things that I thought would work one way doesn't. It is simply not obvious what some of those differences are and that transition period can be a bit frustrating.
^^ Yep, agreed, iOS 7, though apperently copied android, will bring a good thing, as iOS has caught up with android 4.2.2 (seeings Google was lazy and didn't release a bloody new update, and won't go to KLP, and stay on Jelly been), and is now similar in interface in some things, so it will sorta unify it, and make that switch easier.
