Hi, I was hoping to get some help. I am new to Macs and want to get a Macbook. I want to get it from Amazon (Have Gift Certificate) I am debating if I should get the 1.83 MHz with 512 MB of ram and upgrade myself after to 2 GHz of ram. Or Buy the 2.00 MHz with 1 gig of ram. The difference in price is about $200 bucks. I don't care about the extra hard drive space and the small bump in the processor. doesn't seem that important. I don't need the DVD-RW either. If I buy either would I be able to sell the ram and get at least a small price? I know ram is important to a Mac. I really appreciate the help.
