I bought a new 11" Air 64GB model about a year ago. I never really use it or need it. I think I only actually used it maybe less than 15 times since I've owned it and it's never left my house. I also have a Mac Pro 5,1 desktop which is my main machine and I use my iPhone 5 and iPad mini on the go. I hate to think I have a nice machine just sitting there collecting dust and have been getting the itch to sell it for the money, which I could definitely use to help pay down some bills. But on the other hand, I don't want to regret selling it either. As my luck would go if I were to sell it and then a situation will come along like a new job or something where I could use it or would need it. Also it is nice to know I have a secondary machine to fall back on in case my mac pro would ever go down. Not sure what to do. Any advice would be great. Thanks
