Hi, im a new switcher, just bought an MBP, and i love it very much. I planned to buy a mac mini to replace my PC. It's going to be used only for pages, keynote, internet browsing, chat. How much is the performance differences between the core solo and the core duo? I also concerning about the hard disk space, can anyone tell me the actual hard disk space for both model? (solo and duo) the hard disk space is 60 Gb for solo model and 80 Gb for duo model. But how bout the actual size, since my MBP said 100 Gb but actual size is 93 Gb. Thanks
