Perhaps. But Microsoft is almost certainly not really worried about Zoho or Zimbra. But Google? Yeah, that's a different story, and mentioning all three of them in the same breath is a subtle hint that they're all just "bit players", as someone else in this thread pointed out.

I think Zoho is far more dangerous to Microsoft than Google in the long term.

Where Google and Microsoft are both sitting on two cash cows (Add words + Search) vs (Office + Window) and are bouncing around trying to diversify (XBox vs Wave etc) they are not really focused on killing off the competition. However, Zoho is trying to turn Office into it's cash cow and is focused on building a great long term product which means they are going to try and make an equal or better product for less money. Which is why I expect Zoho to build a stand alone office sweet long before Google goes there.
