I'm assuming very few people do this, but I thought I'd raise this as a possibility. I could get a base MBA 11 or 13", and store my entire media collection on an external 512 GB or 1 TB SD or HDD. This would be far from an ideal solution, but I'd have everything I currently have now available on the go. I don't think it would weigh more than an additional 4-6 oz., tops. I suppose there is a cloud solution also, especially for music, but I would prefer to avoid that for a variety of reasons. Does anyone do this? Like I said, I'm assuming not, but there must be a few people who do.
