What should Google do next?

My list of things that Google should do:

1) Google should start a 'Tax preparation software' to compete with H&R Block and the likes.
Features: Should be able to tell what others are doing to save on their taxes.
2) Google Credit Card - should be able to pay bills too.
Features: Should report the amount paid as Sales Tax and help in computing deductible while filing taxes. Should display the store where the same product is being sold at a lesser rate thereby enabling shopper to do a price match immediately.
3) Google Browser - kill IE and Mozilla.
Features: Can think of anything that IE and Mozilla do not have.
4) Google Gas station - kill Exxon
Features: Lowest rate.
5) Google Mart - kill Walmart
Features: Can't think of any right now
6) Google Car - Kill Honda and Toyota
Features: I shall come up with the list when I have some more time.
