PodTech employee and former Microsoft tech evangelist Robert Scoble said today that Windows Vista might not be ready for a release to manufacturing in October 2006, as Microsoft has previously planned. In his blog entry, he compares Vista Beta 2 to earlier Windows betas and observes that while Vista is solidifying, Beta 2 suggests that the future OS is still relatively rough and won't be truly finished in Microsoft's current schedule. Scoble's comments echo prior doubts expressed by analysts and suggest that Vista may well need to be delayed until mid-2007, giving rival Apple an opportunity to steal the limelight with Mac OS X Leopard, expected to be announced later this month and set to be release in late 2006 or early 2007.
