Google Apps Premier Edition is the promised offering for small businesses. It includes 10 gigabytes of mail storage, 99.9% uptime guarantee for email, APIs to integrate with the existing infrastructure of a business (single sign-on, user management, email gateway), 24/7 phone support. Everything for $50 a year per user (there's a free trial until April 30th).

Google continues to offer two free editions of Google Apps:

* a edition for schools, that includes the APIs and 24/7 phone support

* a edition for families and groups that has all the features that were available until now.

All editions of Google Apps* include Google Docs & Spreadsheets and are compatible with Gmail mobile application.

Google's intention is to convince it can deliver "simple, powerful communication and collaboration tools for your organization without the usual hassle and cost" and the package can integrate into an existing environment. Google has learned a lot since last August, when it first introduced Google Apps, and has adapted to fit the needs of a corporate environment. Will businesses adapt to use Google's web applications and trade some features for an always-available online interface?

* You'll notice that Google Apps for Your Domain has been rebranded as Google Apps. </img> </img> </img>
