Does anybody know about this Core M processor strength? I am looking to do very light Photoshop work on the roas and wonder if the rMB would be acceptable to do it. Yes, I understand the rMBP would be the ideal choice on a laptop but because I will only use this laptop sporadically, I would like to get something small, light and easy to carry around. I have a MacPro 12 core for major work on my studio so, the laptop for me would be for a quick revision and small update to any photoshop file while on the road. Thanks for any input.
