I have a 2012 Macbook Air, core i7, 256GB SSD, 8GB RAM. Hardware wise, it's still fine. The only issue it's having is its battery as it is shutting down even when the battery indicator showed 30-40% left. Obviously it is out of warranty. I am planning to take it to a service center since the battery cycle is far from the promised 1000. Even if I did replace the battery, it won't give me the nice battery life of today's laptops as this is pre-haswell, but that's my plan for now if I'm not buying whatever Apple has to offer next week. In the meantime, I want to also explore the kind of things that one can do with an old laptop. I thought about selling it, but since it has a dent, I don't think I can sell it for much. Let's face it, people judge books by the cover. Even though the internals are fine, I'm sure buyers will balk at the one dent on the bottom and negotiate much lower prices. So I am exploring ways to repurpose this laptop. Any thoughts/ideas outside of selling/donating? Any creative ideas outside the usual (eg. HTPC)?
