Ok, well I'm not really that new to macrumors, but I am new to mac computers. The only Apple product I've really owned had been an ipod or two. Anyways I will be getting the 3g iPhone on July 11 and want to accompany it with a new mac in the future. I am really considering an iMac versus the Macbook because I don't need that much portability even though it would be nice. I have a 5 year old Dell and usually just do the basics such as internet, mail, type papers for school, iTunes, and encode dvd's for me new iPhone. My question is: what type of processor do I need? I know 2gb of RAM is almost a must but I am not sure about the processor. Thanks!
