I made the dumb decision to spend over $4000 on a 16" MBP about 6 months ago and only got 1TB of disk space. Right now there's 80gb free and that'll go pretty fast. From everything I've ready the HD is not upgradeable. Has anyone ever bought an external SDD and used a hard drive sleeve so it's semi-permanently attached to the computer? Any options I'm not thinking of ? The last thing I want to do is sell it and buy another just because I need more space. This is what I was thinking of using: http://tinyurl.com/5n76av78 and http://tinyurl.com/msvvrann
