so im planning on buying a mac mini for my parents for xmas and i was just wondering what model would be fine for them for home use. all they need it for is general email and internet surfing. would the base model with the 2.26 ghz be enough or should i upgrade to the 2.53 ghz processor? im also buying a mac pro or imac i7 so money is definately an option so any money that can be spared should be. thanks in advance
