My HP netbook crapped out on me and I'm looking to get something more...modern that can handle iTunes, Chrome, Word, My Docs at the same time without freezing up on me and sending the fan into a frenzy. I hear SSD can handle such tasks like a champ. I will be getting the base 64GB model, 4GB of RAM. Five, seven years down the road will it make that much of a difference? Should I go for Sandy Bridge or Ivy Bridge?
