NetApp… NetApp has offered a powershell based Exchange backup suite (Snap Manager for Exchange) for a while now… They know what powershell is, and therefor know why it’s so important. Time to step up, Full powershell support would be a HUGE win for both the powershell community (major SAN vendor on board), and NetApp (a viable automation framework for the windows admin).
My second choice would be RedHat I want a mono backed Powershell prompt in linux. Microsoft manned up and delivered posh in server core. Now it’s RedHats turn… think about it…. “apt-get install powershell” has a bit of a ring to it!!
