Hi i am a musician as well as a product designer. I dabble in both professionally so i need a serious machine. Portability IS a factor. I have singled out the 17 inch mac book pro (unfortunatly because i live in india the machine cannot be spec'd from the apple site and only base 2.2 ghz one is available here). Anyhow so basically i need input on pros and cons for the machine specifically for music making as well as product design (as well as graphic design). any help and inputs would be extremely helpful.
