I saw a lot of different technologies and devices listed for the "product of the decade", but this one was missing from a most of them, the somewhat lowly USB thumb drive.
The rest is history, with the capacities jumping from mere MBs on the earliest drives to the multi-GB models of today. The ubiquitous thumb drives can now carry portable applications, pictures, documents and encrypted data. They can also be bootable, launch apps automatically, as well play the role of MP3 players, security device and/or forensic device, and the list goes on. The thumb drive is firmly entrenched into the technology landscape of today's modern world.
