Another guess - again pure speculation - is tha having an external adapter
option made certification more difficult in one of the non-U.S. markets.
I believe 1.5, aside from being an update for U.S., is also going to
become the internationalized version of RIS.
I know that in the US wallpacks are popular (for manufacturers) because
they simplify the UL certification process - you only need to certify the
wallpack, and you can then change your main board as much as you want.
Perhaps in other countries (Germany?), things are even trickier and having
an external power adapter puts the device into a different certification
class than a device that is battery-only.
