I have been reading a lot of people who are hesitant to buy now because they want to wait for the merom or santa rosa chips to come out. I have been hesitant myself...but i realized something. With technology, especially apple, you have to jump in sooner or later because if you dont you will never buy another computer again. Things are always going to get better and better. By the time the Santa Rosas are released do you not think there will be whispers of an even better upgrade coming in a few months? That will make you hesitant too! Buying macs is like buying the Star Wars trilogy on dvd...no matter which one you decide to buy there will always be a different version coming out within a year that you will have to buy.
