It appears the Microsoft Mac Business Unit is alive after all as they popped up with an announcement of coming attractions for "the week of July 30th." They'll finally be offering a Universal Binary of the Remote Desktop Client which allows you to control Windows computers from your Mac (thereby hopefully addressing some of Scott's concerns). In addition they're promising beta 2 of the much lamented Office 2007 file format converters with "a significant Word refresh and the addition of PowerPoint (.pptx)."
In fact, the new General Manager of the MacBU Craig Eisler recently introduced himself and called for more "dialog" with customers. At least it's nice to know that things do seem to be progressing up there in the long wait for a Universal version of Office.
Thanks, Space Taker.
