One thing that irks me about libre office is its hacky VBA support. I would think that they would try to support it where I could open an excel file and have the VBA code run the same in both platforms. But a lot of the time it crashes even with that VBA support tag at the top.
If they could provide full support for that I could see a lot of my customers switching to Libre Office for their reports and business tools which in turn would let me switch to it as well.
