Your right, and don't get me started on Google staring a search engine 4 years after Lycos and Go.com. I mean what's the point.
What am I missing?
Even though I think your trolling I'll bite and give you an honest answer.
There are a few reasons:
1) Google Docs isn't that good. 2) clients want a desktop office suite with the option for a web based office suite to do light work when not at their main machine. 3) people who use the online apps are a click away from downloading and buying the desktop version of office 4) its training non paying customers to use office for when they need a more powerful office suite.
I'll reconsider office 1.) when it is free 2.) when it works seamlessly on a Mac.

The free online Office apps work great in Chrome on both Windows and Mac (not sure about Linux).
Last one I paid for was Office 08 for Mac and it was quite buggy.
