Microsoft will make it easier to use Office for iPad by adding iPadOS trackpad and mouse support. This feature will be coming to the unified Office for iPad in the fall. But it might make its way sooner than that. Or at least we're hoping it does. Microsoft is quick to introduce new features to its iOS apps, so we wouldn't be surprised to get this sooner instead of later. And the touchpad support is expected to come to individual Word, Excel, PowerPoint apps, too.
