I am torn between the 13" MBA and rMBP, both 256Gb 8G ram. Both of them can do exactly what I wanted, small video editing, surfing, words/excel. I am happy with the weight on both and the battery life on either one of them would be more than sufficient. The display is the only thing that got me lean towards the rMBP, but does it actually worth the extra 200? And would it make the rMBP holds its value better than the MBA?
