Wife and I are trying out Proton suite. The current purchase price is a bit high, though if we were to find ourselves really sticking with it and starting to see the value, that could change. There are just so many free alternatives, so really need to see the value first at a practical level.

The immediate issue is that we have to be able to share the calendar with each other. With that not being available in the Free sku, we likely won't continue to use Proton long enough to consider upgrading.
