My son will be off to college in the fall. I am looking at getting him a new laptop. I am leaning towards a macbook pro as that is what the school reccomends and services there. Would I be ok with a refurbished? If so what would be the minimum processor speed and memory? None of us are familiar with macs. Does it come with word processiong software? We could also go the PC laptop route but if he gets a virus we will be a state away and unable to just pop in a new hard drive like we do now. I am thinking of buying straight from apple if refurbished or if someone highly reccomends new shopping around. Any tips or thoughts would be appreciated.
