Then that makes sense. I travel with the 12" MB and 12.9" iPP in the same bag, very easy to carry around and still lighter than a single 15" rMBP. iPP is perfect companion for me as I also use it as a secondary display with DuetYou are right it's too big for me as a tablet, when I travel I always will take with me the MBP 15" so as a tablet I like to have smaller one
