Curious to know what my options are if I purchase a 2011 base model Mini and then decide I want to upgrade the RAM in the future. I know I can purchase the RAM and do it manually. Does Apple perhaps also provide a paid service to do this within their retail stores? My thought process is to get a base model Mini, and then get more RAM if I decide to dip my toes in the video editing waters down the road. Also, how much would a future 4 or 8 GB RAM upgrade cost me? Thanks.
