Microsoft indicated that it is working to bring touch-based versions of its core Office apps to both Windows as well as "other platforms" but did not offer any specific launch dates



From Neowin:

While Microsoft has put in features in its latest Office desktop applications that make them more touchscreen friendly, many have wondered when we will get full touch versions of Word, Excel, and PowerPoint. Today, as part of its financial analyst meeting, Microsoft indicated that "touch-first" versions of Office apps are in the works, and they will be coming to more than just Windows.

The statement came from Qi Lu, the head of Microsoft's Applications and Services division, during a technology panel at the analyst meeting in Bellevue, Wash.
