The idea of a mobile ed. subscription is good but let's face it, many of us won't be able to dish out $50 a month. This being said, most of us probably don't need to have access to all the included courses for one month. The cheaper alternative -- access to one free course a month through Logos Now -- is lacking in flexibility: one cannot choose which course and what is being offered may or may not be of interest to the user or may not be timely (in terms of one's most urgent needs).
I would be prepared to pay a subscription "light" that would allow me to choose and access even just one course a month out of the catalogue of offerings even if I cannot keep it, but for a price closer to LN.
