Google first entered the phone retail market when they began selling the Nexus One, but have moved away from doing so as of late. But that is changing today it would seem. Instead of waiting on the US carriers to get their head in the game, they are selling the GSM Galaxy Nexus unlocked for $399. No contract. No Commitment. It is an amazing deal, when you consider the carriers would charge close to $200 for it while WITH a contract. Now you can get this amazing device without renewing your contract and keeping you in control of your service. Visit the Play Store to pick one up for yourself.
Edit: for Non-US readers who may be wanting to have a nosy at the page, here is a proxied link.
