Apple has just updated their Mac Book Pro line. Now they have either a 2.13Gz or 2.3Gz Core 2 Duos. now upto 39% faster. one interesting thing i found in the tech specs: the 15 inch has a single DIMM slot the 2.16Gz has 1 Dimm slot, and the 2.3Gz has 2 dimm slots. both the 2.3Gz 15″ and 17″ comes with 2, for up to 3Gb ram. Which is strange. Why cant i get 2 2Gb dimms in there? Also, these are 64 bit, arent they? [update] the 17″ comes with 2Gb ram standard! SWEET!
