There were a number of things in the Google employment agreement that my attorney suggested were either unenforceable for legal reasons or overly broad, he also pointed out that companies generally don't retain people who sue them (the contract is employment 'at will'). His advice was that if you didn't like it, just quit. That is the low cost way of getting out from under the contract that left little ill will behind. Suing was messy and follows one around to future job interviews.
