Hi
I thought I had already answered your question above... well, to give a more emphatic answer:
YES!
:)
You can find out more about the Subscription here:
http://www.macprovideo.com/plans/
and more about the different versions of NED (for Mac, PC, iPhone and iPad) here:
http://www.macprovideo.com/about/
I suspect the post you read was someone who once had trouble with their log-in and was not able to view all videos on their iOS device at that time. This would surely have been resolved by our Support Team at the time.
The only Education discount we offer is for School, Colleges, etc:

You are free to sign up to the Subscription and stop and resume whenever whenever you wish to.
Hope that helps
