There may be a lot of threads like this, but this is a little different. On Craigslist, somebody offered me $1000 for my Unibody 2.0 MB with apple keyboard, mouse, extra battery and 320GB HDD upgrade. I want to upgrade to the Pro and after discount... it will only cost me $100 after the guys pays me. Is it worth upgrading the Pro? Is the screen a lot better? I am looking to upgrade because this is actually big. Changing it to MacBook Pro is pretty big and the fact that it has the SD Card, FireWire and Backlit keyboard makes it look a lot better. Let me know whether I should upgrade.
