"Even ODF poster child OpenOffice.org has bugs in the
ODF implementation. My favorite is 64237: until version 3.0,
OpenOffice.org implemented the paragraph hidden property backwards.
"Microsoft has opened the ODF door and will be pressured on
better interoperability, so even my inner cynic has a hard time
imagining interoperability will not improve. With Office 2007 SP2
and Wordpad in Windows 7 supporting ODF, the future looks bright
for OpenDocument Format. Has Microsoft turned a new leaf?
Microsoft's recent investments in ODF, PDF, and web standards (in
Internet Explorer 8) are probably more a function of government
regulation or business demand than corporate goodwill. Backed into
a corner or otherwise, Microsoft has done the right thing, but
further work is necessary before the general public can use ODF
transparently in Office."
