I'd prefer a bit more objective reporting with some background included, perhaps this piece at Wired: http://blog.wired.com/gadgets/2007/05/first_look_micr.html

I suppose it's still important what Microsoft is interested in and rolling out, but we should ask ourselves whether it's them, someone who came before them, or someone who comes after them that defines the new interaction method. Like the Wired piece mentions, others have done similar research and there must be startups of various stages commercializing this. Do we know any?
