Why didn't you post this part of the article... seems like it's the most important
"NO, 8GB WON'T WORK
Just for fun we tried the 8GB configuration (2 x 4GB). Though the MacBook Pro will boot and Activity Monitor sees all 8GB, there are serious operational issues. For starters, if you use anything beyond 4GB of real memory, the MBP goes into "molasses" mode
. And if you manage to quit out of the memory hungry app, the reported amount of real memory in use does not recede. At a certain point, our operation was so crippled that we had to push and hold the power button to force a shutdown. "
