On the other hand, my 2014 15" MBP didn't come with less than 16Gb and still packs a quad-core 45w CPU, a decently fast SSD, a crazy good chassis and trackpad and a bright hi-dpi display. I think it's still better than most of the 800-900€ 15" new laptops offered today, but it's not upgradable.

My only issue with it is the battery which will fail sooner or later, but it shouln't be too hard to remove it.
