I don't use my 2Move while walking or while taking public transportation, but I do take it with me to school and use it in the library. It is just too cumbersome to use it with my iphone while I'm on the move. When I plug in the amp to my laptop, it is totally worth it. Either way, I use my super.fi 5s when I'm not at home.
Edit: I guess if I am to address the title of the thread, it would be more accurate to say that I do cary my amp with me everywhere I go.
