Well yes I agree.
Hence my posts earlier / elsewhere that the form factor should have been a little bigger, even if that meant only 10-20% bigger. That would have allowed a slightly bigger screen, and hence browsing may not have been so cramped.
Or why not a bigger circular screen within the same ring footprint? Again, more screen real estate, more browsing possibilities.
I'm not talking about a screen so big that it replicates the big screen browsing of a tablet. But this as it is is smaller than even old iPhone screen sizes.
Even leaving the Halo as it is, there is scope for adding a horizontally scrolling play queue - it's not brilliant does this way on the Moment, but its still ok and offers the ability to jump around to different points in the queue.
But yes, as you say, B&O must be assuming there are sufficient people for whom the predefined triggering is enough. Slightly escapes me though - with the streaming services offering a universe of music, a few set playlists is enough?
A bigger hand held puck with a decent screen could've been cool - looking like a google Nest, it could've kept the outer ring, been able to do all it does now but also browse and display artwork etc. and the display could've used a gyro so that it was always vertical regardless of how you pick up the device.
Not really a technical challenge!
