Did you know that Microsoft has a site devoted to professional photography? Neither did I. The site actually looks more like something from Apple than a traditional Microsoft site. Check it out!
Ye Olde Microsoft:
Pro Photo Page:
There is also a Microsoft Pro Photo Blog: http://www.microsoft.com/prophoto/blog/default.aspx, as well as a cool add-in for Outlook 2003 and 2007 that allows photographers to add details of the client and equipment for a photo shoot appointment in Outlook.
Download the Outlook add-in here: http://www.microsoft.com/prophoto/downloads/prophotoshoot.aspx
