I have been viewing the forum and the internet for the past few months in order to find the best protection and bag for my new MBP. I have decided from all of the reading that the Tom Bihn bags provide great protection and of outstanding quality. Since I am unable to really see the bags in person I am having a tough time deciding which bag will suit me best. I have narrowed my search down to the ID, Ego, and Empire builder. I have been leaning toward the ID but I am hesitant due to possible size problems. I am a current college student so I will be carrying a text book or two and a binder along with my computer, power supply and other various small school items (pencils, calculator, ipod, ect….). Is the ID going to suffice my needs? Any insights would be greatly taken!
