FireWire rekindles on Windows PCs

FireWire is finally ready to ignite. Long after it became a hit on Apple's Macintosh, the super-fast link to digital cameras, scanners, and external drives may soon arrive on a PC near you.

The peripheral port standard, also known as 1394 after its IEEE standard (and i.Link in the Sony version), currently offers up to 400 megabits per second throughput. That's enough to handle videos with little degradation and better colour and resolution than other peripheral ports can deliver, say analysts.

FireWire also speeds up image processing on scanners and digital cameras, many of which now come with 1394 ports. It offers true plug-and-play connection and allows longer cabling than competing ports. The standard first appeared on graphics devices but is now spreading to external drives.

"I think we'll see it pretty much in all PCs within the next five years," says Martin Reynolds, a vice president at the Dataquest research firm.

Lukewarm support from Intel and Microsoft, and alternatives such as Universal Serial Bus that are cheaper to license and support, have kept FireWire off most PCs.

But the situation improved last spring when Microsoft added supporting software to Windows 98, and 1394 add-in cards for existing PCs are now available, notably from Adaptec.

USB-2 and high-speed serial ports are likely to edge out 1394 as preferred standards for slower devices on next-generation PCs, Reynolds says, but the much faster 1394 should remain popular for video editing.

Snider says coming months will bring high-performance 1394-based scanners and printers, and a new generation of faster cameras may arrive late this year.

A new specification that doubles the standard's maximum throughput to 800Mbps is expected by early 2000.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
