At work, our corporate network is mainly all Microsoft. Sure there are roles filled by some linux machines and for our ISP services, its almost all unix/linux. But for email, calendaring, document sharing, its Micro$oft all the way. I’m the black sheep of the office running OSX on a mini. I’m “testing” software, honest =) Due to the nature of the corporate network, I find it is just easier to run the Microsoft office suite which means working with Entourage on a daily basis.
