Hi Guys. How is the iPad pro to hold and use? Does it become uncomfortable after a while due to its size and weight? How about 1 handed? Does it become awkward in hand after a while of laying on the couch surfing or sitting in bed reading a book? How about walking around and using it at the same time? I have an iPad Air (gen 1) and am considering whether i should get the IPP or the upcoming 'iPad Air 3". No plans to use the pencil or keyboard at this point. Thanks!
