I am planning to purchase a Macbook Pro for college in 3 weeks. I am totally stoked about making the transition to an Apple Computer's user. I am planning to either go with the Macbook Pro 2Ghz 80gig 128gpu, or the 1.83Ghz 80gig 128gpu. Both contain the identical superdrive. The Macbook Pro 1.83's are going for $1659, the 2.0's are going for $1849, which are tax free on numerous sites, authorized and nonauthorized. Could purchasing the MBP from a nonauthorized dealer void the applecare 1 year warranty? For instance...B&H Photo/Video is well known and used, but is an unauthorized dealer.
