I was thinking about buying the MBA 11" 64GB as my primary computer. Having looked around this forum I notice many users advising others that not even the 13" MBA 256GB should be a primary computer due to the lack of CD/DVD drive and low storage. I'm guessing i'm in the minority of not having any photos, movies or tv shows on my computer - I only store my music and some documents on it. This means that I am only using about 27GB and have no plans to expand on that as music/radio entertains me enough. My question is (purely out of interest)... how many GB are you currently using on your Macintosh HD (any Mac applies) and if you're using over 256GB, how?
