It has in interesting internal architecture, with 7 parallel processors, allowing speed and power savings. They claim that a single AA battery will last a few months. It runs an OS called 3ActilOS but the site doesn't have very much information on it. The images on the web site look like Photoshop jobs, so we'll be interested to see if the $600 machines that they're selling actually exist.

When in the 2.5 builds the GNOME project changed directions of the ever infamous Nautilus to make the interface spatially oriented I was one of the skeptics. Yet, over the years I have used almost every type desktop configuration imaginable with very few that I found not to like or learn from at least at some points. With this in mind I was bound and determined to find the positives of the spatial file paradigm and, glean what I could from it.

Microsoft is set to include its Services for Unix (SFU) add-on for Windows as an integral part of the next major release of the Windows server operating system, codenamed Longhorn and expected in 2007. Some analysts said the move could eventually sideline conventional Linux and Unix operating systems. A growing number of firms are using SFU, currently a free add-on for Windows 2000, 2003 and XP Professional, because it enables a single system to run Windows, Linux and Unix software.
