I'm planning a 12,000 mile 6-week trip across America to the Arctic Ocean. I have been trying to think through how I'd stay connected. My iPhone has tethering so I was thinking go MacBook Air which has real Adobe Lightroom, Photoshop, Final Cut Pro and full disk access. I really want a new iPad. I LOVE my iPad but I don't now if the new iPad Pro is $600 better than a MacBook Air for my needs.
