Wow. I guess everyone here must HATE those devils over at Adobe for not giving 100% freedom to MS to do anything they want with this format for free, right? Where is the outrage? =)
ODF might be another story..
I agree, this has a lot of potential and I would happily embrace an open format document.
Ahh but MS is free to do whatever they want with PDF, they just cant break it and still call it PDF! Do you see the difference?
It makes a great deal of sense having a document standard that isn't tied to a single vendor.
