Hello, I am considering to buy either the special edition (medium) or the large version of Intuos Pro. Currently, I am using the MacBook Pro Retina 15". I plan to add a large screen monitor (probably 27" or so) few months later. In this case, is it advisable to get the large version? Will there be compatibility issue (e.g. matching the resolutions of both devices) between the rMBP 15" and the Intuos Pro Large? Thanks.
