Coming "soon" in Longwait, er, Longhorn (the next version of Microsoft Windows--due in December,2006) will be Metro, Microsoft's free-licensed printing file format intended to go head-to- head with PDF and PostScript (the venerable, and completely free, de facto standards from Adobe), according to an article from ComputerWorld.

I'm not quite sure what the selling point is, but was amused to note the comments on SlashDot include mentioning "Apparently, everything printable in Longhorn is a Metro document, or can be made one with ease... hey! Kind of like how everything printable in OS X is a PDF."
