I have a 2010 13inch White Macbook, 7,1 2.4ghz, 8gb RAM and 256 Cruciall SSD.
I'm thinking about selling it and getting a macbook air, but not sure how much i'd get for it since its a bit old school now, so to speak.
If white Macbooks had thunderbolt or USB3 ports they would be much more worth. The major leak for these devices is the lack of fast external connections. However, as a corporate laptop it's still good, and in some aspects are better than Air Macbooks: the built-in ethernet port and superdrive unit are welcome features in the daily corporate work.
I think if it's in a good shape, battery with a low cycle count, it would sell for around $600,00-650,00.
