I have a MBP 13 inch quad-core i5, 8Gb ram, 1Tb hard drive from about a year ago from work. I have a budget for a new laptop, enough for a retina MBP (also from work), and is it worth it? Bearing in mind I work in an area where personal use of computers is fine (I bring in my own budget at work), hence using it for photos, is it worth it? The best thing about my MBP is how portable it is (very small), but I do find it is a little slow when editing 100Mb files in CS5. Is the lack of DVD drive a killer? Does the extra bulk make it a pain to travel with (I fly long-haul a *lot*)?
