Is there anything I should be on the lookout for or some guide I can read or is it fairly straightforward? Am I really bound to free up a GB or two or is only a few MBs with the programs/options/drivers I won't be needing? I just wanted to make sure there's not too many options I won't understand that I might leave off that might screw me over in the long run. I haven't made a clean install on any Macs before, so I'd appreciate your input. Is there a way to save any of the settings I have now (went through the initial setup process when I first got it)? Thanks.
