I have a few questions that I'm not tech savvy enough to answer and was hoping some others might know, to help me make a final decision on whether to move to Note iii over iPhone 5S. 1: Can you send or receive group messaging? 2: Can I still use iTunes? All of my 700 gigs of music are formatted on an external mac compatible drive. I am not sure if there are any challenges from switching phones and mp3 formatting. 3: Is there any way to Airplay to my apple tv from a Note iii? I fully realize some of these questions may seem dumb but I just don't know the answers. Thanks in advance if you can help me out.
