Google office doesn't sound overly threatening yet. MS Office is a great software package.
What do you mean read email? They view gmail accounts?
Google Earth concerns me. Seems to be upsetting a lot of governments too and so it should.
I've also started to use MSN Search, just to compare the results. I must say that google brings up a lot of 'spam' as MSN brings up more valid results. Go on, try it!
But personally I don't like search engines, directories are SO much better, when organised correctly 😉
