Use PC at home, in car

VIA ARTIGO MINI-PC ($299): Smaller than a paperback, VIA's new ARTiGO mini-PC was originally designed for hobbyists. But the minuscule box has other uses as well: It's small enough to sit next to a monitor as a stand-alone PC or hide behind a TV to become part of a home theater system. It runs Windows XP or Linux, has a one-gigahertz processor and can hold up to one gigabyte of RAM, which is included.

The ARTiGO, sold as a kit, costs $299 at It includes four USB ports, audio connections, a VGA port to connect to a display, and an Ethernet port for Internet connections. An optional hard drive costs about $65 for 160 gigabytes. The PC runs most applications and can connect to any USB peripheral.

Because the PC is so small, it can fit into the DVD drive bay of a regular PC, creating a minicluster of computers. VIA also suggests using it as an in-car PC. The company calls the ARTiGO a “builder kit,” which is a nice way of saying some assembly is required – expect a tangle of wires and the whiff of solder while you add and remove peripherals and programs.

Kids can keep the noise to safe decibel

ULTIMATE EARS LOUDENOUGH EARBUDS ($40): Parents have been telling their children to turn the volume down since “wireless” meant AM radio, but noise-monitoring has gotten trickier as music has moved into headphones – where sound levels can get dangerously high. With parental concerns in mind, the LoudEnough earbuds from Ultimate Ears have volume-limiting safeguards built into the hardware.

Although safe volume levels are still important, the components in the LoudEnough earbuds also reduce sound-pressure levels up to 20 decibels, or one quarter of the volume of other earphones. They use a standard 3.5-mm stereo plug, which allow the Ultimate Ears to fit just about any portable MP3 player or other audio device.

The earbuds, available in three colors, sell for about $40 and can be found at Each pair comes with two sets of silicone tips in three sizes (extra-small, small and medium) for keeping the buds in place inside the ears – which may even make them appeal to adults who complain that the iPod earphones are too big and tend to fall out.
