Charles Di Bona, a senior analyst at Sanford C. Bernstein and a noted bull on Microsoft, said in a June 10 report that “dampening” adoption of Vista by corporate customers will shave $395 million in revenues and 2¢ a share in earnings from the company’s financial results for the 2009 fiscal year, which begins July 1. According to a Bernstein Web survey of 372 information technology professionals fielded in May, companies expect just 26% of their PCs to be running Vista by the beginning of 2011, down from an estimate of nearly 68% of computers by respondents to a similar survey a year ago.

Wow.
