Hi guys, I've just moved into a new phase of university which requires me to have a laptop, so I'm looking at replacing my old iMac with an Air. So... How much do you think I could get for my iMac? (And what's the best avenue for selling it?) Bear in mind that I am in Australia, however the USD and the AUD are basically at parity so valuations should be pretty similar. My iMac's specs: -21.5", Late 2009. -3.06Ghz Intel Core 2 Duo -ATI Radeon HD 4670 256MB -1TB HDD - APPLE CARE (*Until May 2013*) Thanks guys, any help would be greatly appreciated.
