Going backpacking for 4 months and I have decided to take my Ipad over my laptop (for obvious reasons). This means my macbook will be inactive for four months. What are the implications of leaving a device off for so long if any? Was probably going to sell it when I got back and upgrade. So it would make sense to sell it now as opposed to selling it in four months which could decrease the value. It's a 2010 model which has been taken care of exceptionally. Never been dropped, been case-protected since I bought it, no scratches, no trauma, never over-filled the HDD. What information would I have to provide for it to be valued accordingly? Cheers!
