Microsoft Chemical Team blog released Windows Vista adoption case studies for Eastman Chemical and PPG. The Eastman story focuses on the timing of their refresh cycle and their evaluation of whether to stay on Windows XP or move to Vista. The Vista decision came from a number of factors, not the least of which is getting better control and limiting administrator privileges to their corporate machines. As part of their rollout plan, they did a small pilot to their North American IT group of 350 users in October, 2007, and then to the broader global IT group soon after. After a successful pilot, they began deploying in February, 2008 and expect to be rolled out to most/all of its 10,000 users by August, 2008.
