Here's the story from a link off CNET http://news.com.com/2001-9373_3-0.html?tag=nefd.aon. The company discussed is producing a plug in card that will have a Pentium M and allow a Cube to run as an Intel machine. http://www.danaquarium.com/article.php?story=2005022810275733 "Performance is expected to be slightly below the level of a similarly equipped PC, as the PCube cards must operate with the Cube's dated 133MHz memory bus. U-Power is already working on a solution, claiming an upcoming replacement daughterboard for the Cube will allow it to use faster DDR memory, faster wireless and other features using Intel's Centrino chipset." If this market develops, perhaps there would be Intel plug-ins for current macs that would allow a "switch" in the future using today's macs (with whatever security Apple wants, of course).
