Actually I agree with Balmer. I have an in depth knowledge of Android, iOS as well as Windows, Mac OS X, Ubuntu and all the Linux/Unix underpinnings. But most people I know have fairly basic usage needs. Even those with an iPhone have trouble with finding/using some of the options/settings that would truly help them. But, because it's all still reletively straight forward i can give fairly general 1 sentence instructions to get them where they need to be. On the other hand, with android it's necessary for me to walk them through it step by step.
