Some Gmail accounts quietly jump to 10GB?

I searched the google blogs and other sites, but found only references to google's paid premium google apps accounts that provide 10GB of storage. Is it just me? Is this permanent? And why isn't there more news about it? At 10gb, that destroys most other free email services out there (again), and competes with other paid-for services (*cough* Apple).
