I currently have a 15" with 512 RAM.. It's nice, but I think more RAM would make the mac experience more enjoyable. I'm looking to purchase an extra GB. I'm a mexican student currently residing in Québec, but I don't have any means for online transactions. I'm going to Montreal next week, so I figured that since Montreal is a big city i'd be able to get some certified Mac RAM there. So, do anyone know of a good place to get RAM in Montreal? Thanks in advance.
