Bring it on
Whilst I wouldn'd dispute other's assertions that Google's services are excellent I would seek to remind them that many good services have withered and died due to insufficient marketing, something Google doesn't do in half measures.
If you control the world's #1 search engine and use it to promote your own products ahead of paid advertising for your rivals... it may be legal but sooner or later Google were always (if successful) going to end up being accused of antitrust.
All of their services are free (and the more of them you use, the better the experience, in exchange for all your innermost secrets of course), and have no doubt contributed to the demise of numerous free and charging equivalents. Their dominance of searchvertising gives them deep, deep pockets with which to expand into new territory without concern as to if the new service is sustainable in any normal sense of the word. More money than any venture capitalist could dream of having in his fund.
In many ways I think their behaviour now is much worse than Microsoft's, simply because of the breadth of their offerings, all paid for by searchvertising, and their ambitions to be present at every key point of the hardware and software chain. The eventual result will be an irreversible lock-in - Google becomes the internet (or at least all of its services worth mentioning), and the internet becomes Google, as its financial might allows it to best any company in its path.
Google has, is, and will continue, to distort who can afford to offer services on the internet - let alone make money from them. It is time to break the company up and attempt to redress the balance, before all everybody else is left with is the long tail of the internet service business - and we know how profitable the long tail is, don't we?
