Hello, Any help/opinion is appreciated. My work consists mostly of web browsing, email, media consumption and photo editing. For photo editing I use Photoshop and Pixelmator and usually I edit files that are around 50Mb to 150Mb max. I have a 13" 2013 rMBP, base model and for my needs runs very smoothly. I am considering upgrading to a 13" 2015 rMBP or a 2015 rMB. (both cost exactly the same in my country) Does anyone know how the rMB 1.2 ghz handles editing 150 mb files in Photoshop/Pixelmator? I want speed and for that the 13" 2015 rMBP would be more than enough, but I would prefer the change/redesign and sleekness of the rMB, IF it runs smoothly doing what I need. I don't expect blazing fast speeds with rMB, but I don't want to wait 3-5 seconds to make a change (photo editing) either. Thank you!
