One big difference is that you can choose to use or not to use Google Search. For all intents and purposes you can't avoid using Microsoft products.

You can't avoid AdWords. Have you tried to sell your software products via Bing/Yahoo? There is no audience there.

I am only a consumer so I wouldn't know about such issues. Maybe in the future my opinion of Google will change, but so far my experience with Google has been very positive. I can not say the same about Microsoft.

Did you hear about Google Reader?

[jorgecastillo]

Yes, I didn't use that service & Google Reader was totally opt-in, in no way were people required to use it.
