After just getting an email about the ex2 and its PVR capability… I saw it had a whole section on its dashboard for apps that isn’t on the other my cloud drives… Is this purely a marketing thing or is there a practical reason?
Only marketing.
WDMC can run any of software.
(One limitation: ARM cpu. But all Debian software already recompiled for armhf/armel support)
You want more, than you have? - try OpenMediaVault!
It stabler is also functional, than an original firmware, but slower (Because not optiized for our CPU).
