Hi So after a month of use, im thinking there is something wrong with my new macbook. I have 2gb ram, stock hdd. I log into osx, and i watch activity monitor, i watch as the avaiable ram goes away steadily, over to inactive ram, and after 30 min of light mail, web and itune use, i have 10mb ram left, and 1gb inactive ram. And the macbook becomes painfully slow. Anyone know whats up?
