hey! finally decided to join these boards after about a month of being here everyday trying to decide which powerbook to buy (I have decided on the 15" with the 128MB Vram upgrade) and I have read a lot of people say how great Crucial ram is and a lot cheaper than Apple Ram but i was wondering if it voided the warranty by installing it yourself. if it does then I will just order more a gig upfront and not worry about it. Thanks!!
