It appears to be available only to a few customers at present, as we're not able to see a streaming-only plan on our account or when creating a new one. But tech blog Engadget claims that many of its writers are able to access the plans, albeit (strangely) at different prices. On one computer they're offered a streaming-only plan for $7.99 per month, but on another it's $8.99.
In either case, it appears that this test also brings a bump in DVD rental plan prices. The existing $8.99, $13.99 and $16.99 plans (for one DVD, two and three, respectively) have all gone up one dollar, presumably either to differentiate the DVD and streaming plans or even to subsidize streaming users.
As is the case with existing accounts, these streaming accounts work not just on your computer but through Netflix-enabled devices like Roku, Xbox 360, PlayStation 3, Nintendo Wii, iPhone, iPad, Apple TV and others, and the Starz library is included.
Netflix CEO Reed Hastings has said on a few occasions that he believes Netflix will ultimately be a streaming company. With enhancements to the experience on PlayStation 3, Nintendo Wii and iPhone along with these new streaming plans, the company is getting closer to that reality.
