John made this
famous post 18 months ago, explaining that approx 90% of the Poly users were also Apple users, so Chord prioritised the development of the iOS app and capability first.
The post became famous, because several posters tried to twist his words around, and suggest that Android was considered unimportant, when in fact he was trying to state that the Android owners were also important.
Matt then mentions in the link I added 'Yes the hope is that ......Google will make it available to more hardware manufacturers similar to the approach Apple have with Airplay'.
So overall the Apple owners had the benefit of being the larger user group, plus Apple providing an easier approach for hardware manufacturers to embed Airplay functionality.
In contrast, Google seem to be happy to make it as difficult as possible for hardware manufacturers - which is what has delayed Chord.
