I am thinking about picking up a Macbook as my first Apple. I will use iTunes MS Office and the web. My concern is about the HD size. My iPod alone is a 30 GB although I am only currenntly using about 15. I may want to partition it to use XP also that would be another 15-20 MB. That would leave me with 25-30 GB for OS X and apps. If I fill up my iPod I would only have 15MB for OS X and Mac apps. Do you all think that would be adequate?
