I hate this! I'll take some pics and and maybe a short vid of a favorite song to share with friends but that's it. I remember going to shows before smart phones and I miss it. It really takes away from my experience to have to try to look in between all the damn phones being held up constantly. Also phones of any kind are incompatible with mosh/circle pits, if I'm at a punk show my phone stays in the car. I grew up in the 80's and 90's so handheld tech is optional for me and I'm thankful for that.
