Don’t have their products, but it is interesting watching them as a social phenomenon.
But I strongly disagree.
I found that I was listening to music on my iPhone a lot less often because I didn't want to run down the battery and I also didn't like phone calls, emails and text messages intruding on my music. I missed the days of my old iPod where it only played music and maybe the occasional TV show when I was on the road.
Since getting the Touch, I am amazed at how much better it is as a music device. I can send the audio through bluetooth into my car stereo or send it over to my home speakers through Airplay. I can stream Sirius XM, Pandora, Spotify and Apple Music over it and if I want to download music I don't own from Apple Music to hear it offline, I can do so. Since I got the 128GB version, I can store 20,000 songs offline before even thinking about running out of space. But storing all of them offline is not that important when you can just stream them over Wi-Fi.
I also put my SoundHound app on it so that if I'm hearing a song I don't recognize it, it will identify it for me and give me the option to add it to my Apple Music playlist or create a Pandora playlist. I also have my Podcast app there as well so another thing I can remove from my iPhone.
It's so light that I don't even notice carrying an extra device around and my main worry is forgetting where I put it.
So for those who listen to a lot of music, it might make sense to get one of these iPod Touches and not rely on your iPhone for all those uses.
