Tripped on the charging cable and it went flying (isn't the magnet suppose to come off?!!) Silly...change that, stupid me. Big dent now on the left side -- Laptop operates fine. Anyone know how much the dent depreciates the laptop? I'm planning to resell it now -- perhaps after the new macbook air release around May. This laptop is the late 2010 model (bought in 2011) 1.6 ghz with 4GB ram and the nvidia video card. Would appreciate any advice, someone told me I would only expect around $300-400 if I sold it when the new macbook airs are around the block; so should I just bite the bullet and get the new ones now?
