Hi there, I was wondering if you could help me value my Macbook. I'm planning on upgrading to a 13' Air or a retina pro now that the BTS is available and education pricing as well. My mum who only has an iPad has said that she's in the need for a laptop, though she doesn't really need a mac with the usage it will get with her - but she's said she'll pay me for it and considering my new air would be either £884 or £1039 then I'll need all the help I can get. It's a late 2008 aluminium Macbook 2ghz core 2 duo with 4gb ram, 160gb HDD and Geforce 9400m. Running the latest mountain lion, and I'd be setting it all up for her - wiping the hard drive and probably reinstalling OSX to make it run completely smoothly. Any help appreciated, Cheers people!
