So, I have the option to pick this mac in a refurb with a 2 year warranty. It will be for my wife and she happens to want this body style. My question is will the 2gb of ram be fast enough? Ideally this would last her 2-3 years. Her uses would only be web browsing, iPhoto, and youtube, (streaming video) I can pick up this system for 475.00 in 9/10 condition with the warranty. Covers everything apple covers plus accidental damage. So advice ? do it dont spend more money for better system? thanks.
