This is my second post on MacRumors. I have been reading about the supposed release of new MacBooks using "retina" displays for a few months now. I have my own photography business (bigapplephototours.com) and I am looking to upgrade my computer system from my humble 13" MacBook Pro. Editing photos in Photoshop and designing albums on such a small screen is just tedious and time consuming. I am looking to upgrade to a much larger Thunderbolt enabled 17" MacBook Pro with an external Thunderbolt display. The question I just can't answer is should I spring for this system now or wait until the next evolution of MacBook Pros come out? I do believe that higher pixel density screens will help immensely with photo editing and I will be able to design 24" wide photo albums on a 27" Thunderbolt display while, at the same time, keeping all the Photoshop and Album Design menus and icons on the laptop. Any advice? Thanks.
