Hell yes I use it in public. It's actually my mom's, but the whole reason for needing it is so I can compose no matter where I am. At home, it's too hard for me to concentrate. It's why I can't wait to get my macbook with Logic, because I can just tell all my time will be spent in public places showing off my mac, and composing. I'm actually pretty extreme with "going out in public." I don't just go out in public; I take everything with me. I'll actually take the laptop, a midi keyboard, and an external out, and just sit in Subway after work for hours, or maybe in the park, and just write music. It's pretty funny, actually, because people just kind of stare at the kid at the booth with the keyboard and the headphones with sheet music in front of him. 😀
