Hmmm, the first link is wrong, I don't think Bob Sutor writes in DC's forum yet
This warning comes a little too late, doesn't it? Judging from the recent economic results of Microsoft, one would say they're preaching in the desert. At least, there seems to be a
ray of hope, and as a last resort, we can always rely on HTML and PDF.
For now, and after all the battles between the different formats and the proposers, we're still in the beginning, we didn't move, not even an inch. The situation is exactly the same as it were with old Microsoft binary formats, they work everywhere, but you get the best results with the app that works with them natively (note that even the same document in the same version of Microsoft Office looked different between computers).
ODF and OOXML have the same problem, they work everywhere, but the layout always bork somehow. Difference? OOXML is winning by a long shot, not only because Office 2007 has a larger installed base (no discussion there, it's a better app), but also because at least Microsoft provides viewers for their formats, while Sun... provides nothing! (OK, you can use Universal Viewer with a plugin as a viewer, but it's not nearly the same). One would expect enterprises to install plugins for ODF in Office, but what about individual users? How many are aware that even ODF exists? This battle is exactly as the one in HD formats: lots of money burned, lots of discussion, but nobody is paying attention.
Call me when it's over, for now I'll use the only real interoperable format: PDF. After all, even HTML breaks depending of the browser, and that's a defined standard...
