okay. good chance i am getting the $1200 macbook this Christmas. 2g ram and 160g HD. Should i bother with running Leopard and Vista on it? Would having Vista on the macbook take off too much from the HD? how many gigs is vista? And should i go with bootcamp or get Parralels? my uncle has parralels on his iMac and it is really nice, but how does it work on the macbooks? would settling bootcamp be the better alternative due to functionality on the macbook? And, a friend of my dad has unlimited liscenses for all the vistas (IT guy), and i am not sure which version would be best on a macbook, so which one is best?
