We've traversed the acronym laden landscape of VoIP for you, and present you with the PC Authority guide to VoIP: what it is, what kinds of services you can find, what savings you can expect to make and how it is that you can go about setting up VoIP for yourself at home.

We know you want to play games, so we've put 18 PCI Express graphics cards under the microscope to see who really does the job the best.

It turns out that Microsoft [I]is[/I] bringing out Windows XP Media Center Edition in Australia, but until such time as it materialises -- and Microsoft Australia is being very sketchy on the dates -- those of us looking to integrate our PC media files with our televisions and hi-fi systems have to turn to bridging solutions.

The D900T has to be one the most impressively kitted out notebooks we've ever reviewed. Now, before you go running off with a fist full of readies, this notebook isn't available as such to the general public. Rather, resellers of Todaytech's notebooks can order them in whatever configuration you want. Or if you'd rather -- and we quite like this option -- you can order the notebook stripped of most options, and configure your own from spare parts or cheaper parts if you think you can do better on pricing.

Finding a good PC or notebook for the family is not as hard as you might think. PC Authority  puts the latest models to the test.

The Lexmark P6250 is a not just a photo printer as such, it's also an all in one multifunction device: printer/scanner/copier and media reader. You might be nodding to yourself with the obviousness of an all in one printer winning out over tiny single use photo printers in this roundup, but to be honest the distinction is not just made because of the broad functionality and applicability of the Lexmark P6250.

With the prevalence of Net connections and all the good things a connected society brings such as community, the ability to share ideas and the openness of information, comes the flipside of digital life -- hackers, spyware, viruses and spam.

The TViX is a fairly small box, roughly about the same size as a good DVD box-set, but inside it's got some amazing smarts. This also technically isn't a media streamer as such - it's more a media cacher thanks to the 80GB hard drive inside.

Digital video is a rising star, with DV camera sales increasing from year to year and digital software sales to consumers and enthusiasts alike also on the rise.

When we think of SiS graphics, we usually think of low cost, low-end cards or integrated offerings for the entry-level 2D market, with the possibility of some rudimentary 3D capabilities thrown in.
