>you transfer music to your phone without using iTunes

Can be done

>transfer a file via bluetooth to another phone that's not an iPhone

Can't be done (AFAIK) but is possible to transfer using more normal and useful internet protocols.

> install an app that wasn't released on the market without jail-breaking

Can be done. I do it all the time.

Can be argued that iOS not operate exactly as Android, and the opposite. Some operations are more convoluted than others (in both). However, iOS work, in average, better for the end-user than the alternatives (is very telling that the evidence in how Android is best than iOS is, mainly, in niche cases, complex operations, dev-stuff, and things that are not normal for the average user).
