They also have diff finishes, but that the least in SPECS we usually look at. If you're looking at program power, I'd choose the faster RAM and more storage. RAM can differ a lot in price and is usually a more expensive upgrade, but your RAM access power may mean something to you. HDs are the cheaper upgrade (& some have 3 year warranties) and SSDs are dropping in price as they're getting settled in demand (but I'm not familiar with specs or anything else, yet). Except, SSDs boot up your system much faster, so that's where the Operating System should be located. Saving the HDD for storage of images, music, and programs that don't require speed.
