If the '90s were the Internet era, maybe the '00s were the mobile decade. Technology packed ever more power into ever smaller devices, putting portable electronics at the leading edge of innovation this decade.
Shrinking tech unshackled the Web from PCs, PCs grew small enough for a clutch purse, and high-quality cameras fit comfortably in a hip pocket. Even video games, once the hypnotizer of only the young and pudgy, were unchained for a new form of freewheeling, arm-flinging family fun.
With freedom of movement in mind, here are the top tech innovations of 2000–2009:
Thumb drive (2000). The now ubiquitous key drives, or thumb drives, hit the market in early 2000 through a Singapore company called Trek 2000. Trek initially sold its USB flash drive overseas as the ThumbDrive, while IBM marketed one here that it called DiskOnKey. The names in some form or another have stuck. The first models held only 8 megabytes, which pales next to today's top drives with 32 gigabytes. But that 8 MB was eight times the capacity of a floppy disk, then the standard for moving data via a hand or pocket and a "sneaker net."
GPS (2000). The little screens that now guide drivers and hikers through their respective wilds were technically possible before the millennium. Just ask the military. But in May 2000, the Pentagon loosened its grip on the GPS satellites, allowing civilians to enjoy the same precision in knowing exactly where the heck they are. The result was an explosion in GPS devices (including Garmin's Nuvi 250). This may, however, be the only decade for the stand-alone navigators. Sales already appear to be stalling as consumers increasingly get their directions from smartphones, which rely on the same 24 satellites in Earth orbit.

Digital Elph (2000). Digital cameras were around in the 1990s. But they were clunky compared to the PowerShot S100 Digital Elph from Canon, which set the standard for truly pocketable point-and-shoots. A steel case added to the camera's sleek look, which is echoed 10 years later in snapshot models from Canon and others. The camera also captured a hefty 2 megapixels of data, producing 4-by-6 prints that rivaled those from film models. Cameras have gotten even thinner and more powerful, but none were more influential.

iPod (2001). Not even Apple knew the runaway hit it would have with its MP3 music player. The groundbreaking "click wheel" simplified navigation through thousands of songs, and the partner iTunes software made a huge leap in easily linking the portable player to a desktop computer. The software initially worked only on Macs, as some say that Apple saw the player as an incentive for its computer sales. The company soon saw too much gold in the iPod itself and made iTunes compatible with Windows PCs. After announcing the iPhone, Apple dropped "computer" from its company name.
BlackBerry smartphone (2002). The BlackBerry had already become a corporate favorite for its wireless E-mail. But the brand took off when Research in Motion married a phone to the popular thumbing keyboard. Others had fashioned similar combinations, including Handspring (and then Palm) with the Treo line of phones, and Nokia dominated the market overseas. But nobody here could match the growth of the BlackBerry line of smartphones, with its reliable and secure E-mail system that was loved by newly connected executives across North America. At least not until the Apple iPhone. The BlackBerry 5810 started it all in 2002—though you needed a headset to make calls because that first RIM smartphone had no microphone or speaker.
