I have owned and used 7 Android devices. They're complicated, klugey and inconsistent in interface from manufacturer to manufacturer. I support a thousand users who carry iPhones, and about a hundred who carry Androids. Get way more "how do I" questions from Android users, and almost every one is a new adventure to figure out.
When I bought my first Mac, after owning, supporting and building Windows computers for 20 years it took me about five minutes to be productive with it, and about a day or two to become proficient.
And Microsoft didn't develop Skype. They bought it.
