I bought my dad an iPod last Christmas. He uses it all the time. He has no problems using it.
I recently bought a Nexus 7, and showed him. He had a few questions, but caught on fast. He even downloaded an app without my help . All I had to do is point to the Google Play icon. He logged onto the app and used it.
He admired the JB 4.2 voice input. We tested it out in a notepad app, everything he said came out perfectly in text.
We found a hunting app on Google Play. He said he wanted it on his iPod and searched for it, couldn't find it. I researched on Google for it. Sure enough, it didn't exist for iOS. Ironic isn't it?
He also liked widgets, the back button, changeable keyboard, and the PowerAmp app. His favorite feature is the ability to drag and drop files from his computer. BTW, he hates iTunes.
Overall, everything he did with his iPod, he did with my android device with no problem. There are some hidden features that he didn't know about and I had to explain to him. These features don't exist on iOS.
