I have a 15inch Macbook Pro which was purchased in 2010, spec as follows:
Originally released April 2010
15.4-inch LED-backlit glossy widescreen display (1440 x 900 pixel)
4GB (2 x 2GB) of 1066MHz DDR3 SDRAM
500GB Serial ATA @ 5400 rpm
8x double-layer SuperDrive (DVD±R DL/DVD±RW/CD-RW)
NVIDIA GeForce GT 330M graphics processor with 256MB of GDDR3 memory
I originally bought it to replace my desktop with the intention of playing 3d games etc. In reality I have barely used it for gaming and really don't need the power that this laptop offers as I mostly just play online poker on it and use it for the web etc.
I am looking to swap it for a new 13inch Macbook Air as I'd like something a bit smaller that I could take on the train if desired.
I'd ideally like to make the swap in person. I live in Crawley and work in central London and would be happy to drive a reasonable distance to make the trade.
