I was just wondering why all Apple laptops can only hold 2 gigs of memory. Most pc makers offer 4 gigs of memory in their laptops, especially 17 inch computers. It just strikes me that Apple has a desktop that holds the most memory in the world, but yet their laptops are faily low end. Even if there are only 2 Dimm slots, there are such things as 2 gig memory modules. Also, there is no reason that the 17 inch does not have 4 Dimm slots. Anyone know if it is possible to put 3rd party memory more than 2 gigs in a Macbookpro?
