We all saw it coming.
"Google Apps Premier Edition is available for $50 per user account per year, and includes phone support, additional storage, and a new set of administration and business integration capabilities." (source)
And what does your $50 buy you?
10 gigabytes of storage per user
APIs for business integration (e.g. data migration, user provisioning, single sign-on, and mail gateways)
99.9 % uptime
24x7 support for critical issues
Gmail for mobile devices on BlackBerry.
Surprisingly, Google is making advertising "optional" for these business accounts.
Release the hounds.
