Hi, I found a deal on craigslist for a MacBook Air (Rev. A) for ~$500. It is covered under the standard Apple warranty until September, so I can buy AppleCare. It's the standard Rev. A base model. I have heard of the issues regarding this revision, but I feel like the deal is a good one. I will be using it as a secondary computer; I have a 13" MBP as my main one. What do you guys think? Thanks in advance!
