Well it's quite simple really, DJI have produced these super dooper and super expensive Crystal Sky monitors and want to increase the sales of said monitors.
On the other hand pilots are quite content with iPads and the like, so why would they want to buy a Crystal Sky?
Simple.. Make the Apps and the latest firmware render the iPads etc. useless and pilots will be forced to shell out on a new Crystal Sky!
Oh and while they are at it.. ensure the latest firmware cannot (easily) be rolled back..
Clever strategy to boost the sales of the Crystal Sky don't you think?
