The remote is always instantly on - it doesn't need to be activated and the app loaded before you can adjust the volume. Also because you use it for nothing else, you don't have to interrupt any other use - unlike your phone.
Would you like your TV to comr with no remote controls? It's so useful but such a pity that the M33 takes little advantage of it's features - unlike the M12 and M32 that use the identical remote.
Thanks!
For me, I wish that all our remotes could be app-based, but was looking for arguments the other way.
