Excerpt: One truism of modern technology is that everything gets smaller. Computers used to fill rooms. Hard drives that stored an incredible 5 megabytes of data were the size of refrigerators. Cellphones used to be the size of a military walkie-talkie. Thumb drives, also known as flash drives, or memory sticks, used to be the size of, well, your thumb. But that’s no longer the case. LaCie’s MosKeyto makes the average thumb drive look as big as Shrek’s thumb.
