I'm kinda stuck on deciding whether I should buy a case that has a built in Bluetooth keyboard or just buy the Otterbox Defender and Apple Bluetooth keyboard. I'd only use the actual keyboard if I were to have to take notes for classes I don't normally take my laptop to, so not very often. However, the Apple keyboard seems kind of large and inconvenient to carry around at school. Would you choose this or the Otterbox along with the Apple keyboard. Thanks for any input.
