Long story. I've had two sticky keys on my macbook pro retina 13" in (4GB) for the past two months and finally got it into the apple store to have them fix it. I thought that it was perhaps food stuck underneath, but unfortunately, it's a bigger problem: liquid spill. I had gotten it for $1299+. I was dumb I remembered yesterday, then, that i had spilled orange juice around my macbook around 2 months ago. I wiped it off, thinking it was fine and didn't think of it at all until yesterday. It hasn't really affected my macbook in other adverse ways besides the two sticky ones. If I think hard enough, I guess there were some skype sessions when the other end couldn't hear me. But it never ocurred to me that something bad happened to it because I had just gotten the laptop 3 months ago new for college. My dilemma is, should I keep using it until another bad thing pops up, which it eventually will? Or, should I sell it off for my highest offer right now of $650, and buy a refurb with my added $100 apple gift card, totaling my costs to $350 for a new refurb macbook? It works fine, but the sticky key on the space bar has always annoyed me for the past two months and Im scared of new problems arising such as the laptop turning off randomly or other malfunctions. So, what should I do?
