Writer 3 vs Word 07

We can all agree that OO.o Writer can beat Word 2003, but against Word 07 is a different story.
On the top is Writer and the bottom is Word. Writer is based on MS Word 2000. Word 2007 has the new ribbon look, which goes really well with Aero. Word 2007's spelling and grammar features have improved a lot since Word 03, but Writer still does not support grammar corrections. Writer 3 loads almost twice as Word 07, but Word has more features. Writer 3 even has support for the new .DOCX format. Also, OO.o had support for PDF for many years, while Microsoft just added that feature in Office 2007.
