Really? Can we realistically do a better job when millions of users want 
another set of MS features each and every day?
When downloading the Microsoft *viewers* for WinWord, Excel and 
Powerpoint, these three *viewers* cover the file formats doc(x), rtf, 
xls(x) and ppt(x). Their download size is close to the download size of 
OpenOffice.org (single language, no extensions but including additional 
components, 4 macro languages and read-write access to dozends of file 
formats).
How much coding does it take if you are aiming to 100% compatibility 
with their proprietary file formats?
What does it mean that the specification of OOXML weighs 8 times more 
print pages than the specification of ODF?
