J Allard leaving Microsoft over Courier axing?

Well, it looks like the Courier's demise could be having some far bigger implications for Microsoft than anyone had suspected. According to ZDNet's Mary Jo Foley, Microsoft's Chief Experience Officer and CTO for its Entertainment and Devices division, J Allard, has been on sabbatical from the company for the past short while and is "unlikely to return" -- all due to the fate of the Courier. According to Foley's sources, Allard was "the champion" of the Courier, and had reportedly made his feelings about the device and its ultimate demise clear on numerous occasions -- including, of course, directly to Microsoft CEO Steve Ballmer. According to another of Foley's sources, things eventually got so heated that Ballmer "showed Allard the door" because of their disagreements about the Courier's potential. So, did he jump or was he pushed? Microsoft isn't saying, and Allard is seemingly nowhere to be found.
