I don't expect that to change, and it may not need to for the company to be successful, but it makes you ask if it's really better to support PC use if the support is inferior. Not investing in Mac hardware puts the church at a disadvantage with this software. The biggest issue we had was with releases/support for PC lagging so far behind Mac.
Also, the multi-user features coupled with cloud sync make team collaboration so much more efficient. The SongSelect integration is by far the most useful feature for a church that relies on SongSelect for lyrics etc. I love the integration of various media types and source material platforms. We were able to expedite the service preparation process incredibly with the media integration available through ProPresenter.
