I'm very interested in picking up a refurb or clearance priced 17" MBP, but I'm not sure which direction to go on the options for screen resolution and hard drive. -Screen Resolution: high resolution, regular resolution, or does it even matter? -Hard Drive: 5400rpm, 7200rpm, or does it really matter? I'll be using the laptop mostly for web surfing, word processing, and perhaps some MMO gaming. I'm not sure which functions benefit from higher resolutions or faster hard drives.
