Can iWork / Keynote on the iPad open and/or save Microsoft PowerPoint (.PPT) files?

Keynote, iWork's presentation creation and editing application, can import both Keynote and Microsoft PowerPoint presentation files. However, iWork cannot save in PowerPoint (.ppt) format. Keynote can save files in either Keynote or PDF format.

PC users can view Keynote-created presentations online at iWork.com, however.
