Selling a 15 inch MacBook Pro with a 2.4 GHz i5 processor, 500GB Hard-drive, 8GB of 1333 MHz DDR3L SDRAM , 8X DL SuperDrive,Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system, Facetime HD camera, Thunderbolt. Should this last me for two years? I want to use Photoshop and Adobe stuff on it. I have a 2010 13" 2.4 gHZ base model with 4gb ram. This one has 8 and I would have already upgraded. Can the Applestore test this computer for any malfunctions if we meet there?
