Hi, I'm just about to buy a 13" rMBP and am torn between the base model (8GB, 2.7ghz,128GB) and an upgraded ram model (16GB, 2.7ghz, 128GB) costing ~ £160 more. I need a hand deciding, I'm a student so that additional spend would be good to keep if the additional ram isn't needed. On the other hand this is something I'd like to keep for at least 5 Years, so while my needs aren't crazy; a VM in the background, and a number of chrome tabs plus word/spotify ect. The odd bit of xcode and Photoshop/iMovie too. I'd still like to be able to do all this with fair snappiness in 5 years so am I best to upgrade my RAM or is 8GB enough? Thanks guys. Much appreciated.
