I am considering defecting from iPhone. I think I may have to keep the iPod and iPad (unless something as good can be shown to me very, very soon). But what about the music I have purchased on iTunes. Is there any way to get that onto (for example) a Galaxy S3? And all the gadgets that connect to the iPhone (stereo, docks, car stereo etc)? Can they be converted or are there equivalent items? Is there a real alternative to the iPad that does things as well?
