Storing all your important corporate information on a Google hosted service is like storing all your bananas on the Planet Of The Apes.

That having been said, I'd rather Google's apes sniff my bananas than MonkeySoft's apes. A segment of the company I toil for was using JotSpot prior to the buyout and if Google can do a fair job of integrating their search and Google Docs apps into the service, they could potentially have a strong contender in the information management space.
