Hi all, Looking to get a new mbp as my 2011 is taking a dump. My main uses are photoshop and Lightroom followed by Microsoft office and Safari. Will I be ok with the 2.6 13" with 256gb flash storage or should I go with the 2.8 with 512gb flash storage? Last option which I will only do if folks think it's the best way to go is the base 15" 2.2 with 256 gb flash storage or the non 5k base 27" iMac... I am completely flexible between desktop and laptop Looking to purchase today your help is much appreciated!
