Microsoft vs. Open Office: Getting to the Bottom of It, Once and For All

[Sofaspud]

The why of it is simple -- Money, dear boy.  RTF is closed, therefore, if you want to have hassle-free RTF usage, you must use Microsoft products.
Personally, I'd say don't use RTF.  I'm not sure why you would want to when you have other, less problematic, more reliable, and more robust solutions available to you, that are in fact cross-compatible in ways that RTF is not and never will be.
ECSNorway: I -think- Google Calendar can, and I think Gmail can for contacts.  I haven't tried it, however.
