I do not own Logos Platinum and do I think it would be worth the cost for me to upgrade - just to say it's more than personally I would ever need.
I've enjoyed a few of the Mobile courses and have even ordered a few more, despite the fact that recommend a platform higher than I own.
But might I suggest that It would be beneficial if we might know the reading list for each of the courses before purchasing the course.
It might even be added to the cost of the course at a discount price for those of us without the resources.
