Of course makers may want to ditch Android.
They are selling one system to cover mp3 player, phone, tablet, GPS system and even PC.
Whereas Apple sells individual well defined items.
SO they have an mp3 player, a phone, a tablet, a GPS tablet, a laptop and a PC.
They can sell 6 items all covered by one Android device. A far better way to 'do business' and one that all manufacturers want to emulate.
