Hello guys! I'm thinking about buying a Macbook, but I'm quite indecisive, because I don't know which one to choose. I'm also not really familiar with the specs, like is i7 better with lower Ghz or i5 with higher Ghz, and all that stuff. I would use it for basic stuff (browsing, chatting, watching videos, school etc.) and for photo-editing in Photoshop (I'm doing photography) and maybe video editing in the future. I'm a student so my budget is quite limited, that's why I would like the "cheapest" one if possible. I was thinking about Macbook Pro 13" 2.7 GHz Retina display, 128 GB, because it has higher Ghz, but I'm not sure if I need that much. Also the storage is a bit small, but I could buy an external disk. I would be really thankful if somebody could explain me how to choose the right Macbook considering the specs, like what is for what, where do I need invest more money and where don't. Thanks in advance. Have a nice day!
