I have a 9.7" iPad Pro, but I've been considering the larger version since it really is a computer for me. (I have a work PC, but at home and on the road I only use my iPad.) I checked out my carrier's site last night to see what the pricing is on the 12.9" model and they were "sold out" of every single color and size configuration. I've seen an article here and there about possible March release of a new 12.9" Pro. Maybe that's why? Coincidence? For those of you who already have one, is the larger size a plus or a burden? Thanks
