Okay so my parents surprised me for Christmas and they got me a MacBook 2.16GHz(I wonder how long they had it for). I have been using PC's for 5 years now and I've been wanting a Mac for a long time. I have not regretted having it and I personally think its the best thing in the world. It had the Leopard Drop-In Disk and the iLife '08 drop in disk...so I had some questions about the RAM and memory or both... 1.Are RAM and memory the same thing? If so, is the RAM on a 2.16GHz hard to install 2. Should I upgrade RAM and will I see a dramatic increase in speed or performance? 3. What kind of RAM do I need and how much is it gonna cost? I would like to go for the maximum..but I'm not aware of the prices so either 2GB or 3GB of RAM altogether, but yeah so does anyone know an estimate of how much it will end up costing me? 4. What brand of RAM? Sorry if I'm asking too many questions but it would be great if someone helped me!
