I'm starting a new psychology program and I've decided to purchase a new Macbook since my old Pro was stolen. Before I go any further I just want to make note of something, I have a PC that I do all the heavy lifting with, or at least, most of the heavy lifting. Now, I've read through countless threads here on Mac Rumors regarding the whole "4gb vs 8gb" argument and I've concluded (correct me if I'm wrong) that 4gb for word processing, front end web development, web browsing, and light video editing is sufficient and will be for the next two to three years. My main question is, will 4gb be sufficient for working with XCode? I am a beginner with iOS development so I can't imagine working on any large projects for the foreseeable future but I'm wondering if 4gb will be enough for xCode + Safari + iMessage. Any insight is greatly appreciated.
