Sure but this looses appeal for me. I still need macbook nearby and both devices need to be charged. If I'm in plane i dont want to remove my laptop from hand luggage or draining both batteries. This is just slightly better than someone connecting ipad to external monitor and logging with remote desktop to cloud computer and pretending ipad is good for software development.
