Ok here's the low down: I thought I wanted the base retina but after seeing some threads I'm unsure whether to go for the higher spec non retina. I'm currently in uni, I game quite a lot and when I leave uni I will probs be doing a job that will involve photoshop (I do advertising). The 13inch is out of the question so don't suggest that. The key points for me pro retina are: Thinner/lighter - make it generally more pleasant to haul around. I currently have a 17in Dell which was a big portability mistake. I rarely move it off my desk and it's a major operation to take it into uni (some exaggeration). More pages on the screen - major for me, I'm a page addict and I dislike switching from tab to tab. I would rather luxuriate and have all the info I need on the screen, especially useful for writing assignments which requires many windows side by side. This is probably the best reason I've got for the extra pixels. I know stuff will look smaller but is that a big deal? More video ram - kind of speaks for itself, although a concern of mine is that the retina occupies that just for having more resolution. Not as reflective - again, I've used other peoples macs and it's annoying seeing myself with full brightness in modestly lit situations. SSD - faster and more reliable, I've had a hard drive failure before and its not good. I know, back ups stop this but I'm lazy and don't do it as often as I should. The capacity is a non issue as I keep my media on external drives, leaving the internal for my programs and music (is sufficient) Neutral points: base ram better, I know you can improve the older design's so it's not a real problem. Hdmi port means I don't have to buy an adapter. Fans are less loud but I'm not that bothered. Are they more effective though? Edit: non-upgradeability I don't think is a concern of mine. The specs of the retina are more than good enough for now and will last me into the future. (longevity is a plus point) Insights, views, opinions?
