Get every National Geographic since 1888 on a 160GB hard drive
What you see here is the beginning of the end for the librarian. It's also great news for trees and climate change! (Unless someone can turn around and tell me that a hard disk drive is actually more harmful to the environment than 120 years worth of printed magazines).
For a third of the price you could also get the entire collection on six DVDs... but that's not quite as cool, is it? They also mention that 100 of the 160GB is freely available for your own use -- or future content updates, because the National Geographic shows no sign of slowing down yet!
