Great stuff -- BUT we've actually had Photo RAW support since XP days !! http://www.microsoft.com/download/en...s.aspx?id=8802
Note also that it's not always easy for MS to supply this stuff -- since new cameras appear very frequently.
I still think that if you ARE a user of any camera RAW format you would probably be better off in using either Photoshop CS4 / CS5 or photoshop elements.
Note that Photoshop Bridge supplies a decent photo RAW viewing browser too.
