I consider myself reasonably savy with regard to Unix... though I haven't used it in 10 years. Here's my question: Given that I consult at Fortune 500 companies, how realistic is it for me to switch from being a Microsoft slut to being a Linux user? Most of the people I work with use Outlook, MS-Word, MS-PowerPoint, MS Project, and Visio. My primary concern is editing and routing documents shared by a project team. Thanks!
