So I'm about to start college(this monday actually) and I'm really tight on money with books, tuition etc., I have about 30 bucks to spend and I'm wondering whether i should upgrade to SL for the 30 or Buy 4 GB of ram for my macbook. (sale at frys for 30 dolllars). Which of these two options would end up making my mac faster? what i really care about is speed. so what would you do?
