2009 White Unibody Macbook for $500. Trackpad Doesn't physically "click" but the cursor moves the ouse around, He just explains it as it is not able to push down to select anything. I asked if there was any water damage or spills and he said no. I however will be bringing my handy tool set to make sure the water indicators aren't pink or red. My question to you, is 1. Is 500 a good deal, or a great deal? what is it worth AT LEAST? 2. Where are the indicators located inside the macbook? 3. has anyone experienced this problem and can confirm its not a water damage problem 4 Does anyone think it IS a water damage problem, and give your reasoning. THANKS!
