Novell has just launched a Vista/Linux comparison site, in anticipation of the Jan. 31 arrival of the retail version of Windows Vista. Unsurprisingly, Novell's site reminds users that SLED 10 (SUSE Linux Enterprise Desktop) is already here, and promotes it as the better upgrade for Windows business users.

While Microsoft and Novell may be partners now when it comes to Windows and Linux interoperability, don't think for a second that they've become bosom buddies. In this Web site, Novell bashes Vista both on TCO (total cost of ownership) and on usability grounds.

Novell claims that "With SUSE Linux Enterprise Desktop 10, you receive over 90 percent of the functionality of Vista and Office for less than 10 percent of the price." In the pricing section, Novell walks you through the cost differences between SLED and Vista and Vista/Office 2007.

When it comes to dollars and bytes, SLED is the clear winner. It only costs $50 and it comes bundled with a full-function office suite, OpenOffice.org 2.x. IN contrast, the Windows Vista Business upgrade price is $179. If you buy straight retail, it's a cool $299. Vista, of course, doesn't come with an office suite. Microsoft Office Professional 2007 for Windows Vista costs $499 per user at list. The upgrade price isn't cheap either, at $329.

Of course, all this pricing information presumes you can run Vista on your existing PCs. SLED 10 will run on any recent PC. Vista, for all practical purposes, requires a system with at least a 1GHz 32-bit or 64-bit processor, 1GB of system RAM, a graphics card that is DirectX 9-capable with WDDM (Windows Display Driver Model) drivers, and at least 128MB of graphics memory.
