Hi, I'm looking at the 13" MBP, but looking at benchmarks the 15" is significantly faster at most tasks (they show anywhere up to a 50% increase in performance). I've looked at the 13" in my local store and love it, but just want to be sure I'm making the right decision. I'm also not sure about 256 Gb or 512 Gb SSD option - apart from productivity apps, and Parallels running the dreaded "other" OS, which itself will be running dev tools for that platform. For storage I intend to use a flash drive for on the road (backed up of course) and a Windows-based file server when at the office. This brings me to AirPort. I know Time Machine works great with AirPort, but can you also use AirPort as regular network storage? In this role it would be used as a backup drive, not regular file access.
