Hello everyone. I would just like to say hello to everyone as this is my first post on this forum. I just purchased my first piece of Apple computing hardware today, a 12" 1.5ghz powerbook for school. I just had a few questions about my memory options: Am I limited to a specific size/amount of RAM? I will be using the computer for Microsoft Office applications, games, and the rather rare instance of video editing. How much RAM do you reccomend? Can you point me in the direction of a solid internet retailer? Thank you for your help! p.s. sorry if this has been covered already!
