Hello to all, I'm looking for a small backpack or messenger bag for my macbook pro. I'll ONLY be carrying the following things: 1. Macbook Pro (inside of a neoprene sleeve i already own) 2. Power cord 3. External hard drive Thats all! Right now, I have a HUGE backpack that I bought a few years ago. But I just graduated and dont need all the space for books, etc. I just want a super small backpack or messenger bag that has just enough space for these components. Does such a thing exist?
