i'm planning to get a macbook with 2.0GHz, 4GB RAM & 250GB HD but want to make sure i'm making the right choice. i usually do a lot of web browsing, iTunes & movie watching, photo editing and occasional photoshop & illustrator but not much gaming. are these specs good enough for me? let me know what u guys think.. i still got 3 days before i purchase my very first mac. thanks guys!
