Jim Allchin finally retired from Microsoft on Jan, 30th 2007 following the public release of Windows Vista, after almost 17 years with Microsoft. I have tremendous respect for him. He has been among the pioneers who shaped 2 of the most popular client versions of Windows today. His leadership on Windows Vista has been commendable. It took great courage and forethought to abort midway into the development and start again from scratch. I wish him good luck into his post-retirement life.
