The inline adapter is still slated for production, but due to supplier
issues didn't ship with the ramp units. Instead, the ramp units
(and some early production) will ship with a stock white wall-mount
unit.
Would you rather that I held up your test unit while we waited
for the supplier to

Thanks, that's good news!

The chart is of limited utility. For example, Argentina and Oz share
the same socket except that the pins are different lengths, so that if
you try to import an Oz plug into Argentina, you will get stopped in
customs. (Lesson learned the hard way.)

Are you having them think of daisy-chaining, too? Like older PCs

Hi all,
Does anyone have plans to give 2 extra meters on the power cord of the
XO-1 transformer, maybe in time for Gen 1.5?
I don't have a clue of the usage scenario on underdeveloped countries
but it sure would come in very useful to have some extra length on
this power cord. At least I feel

We are considering changing from a wall wart
design to an inline design, for the following reasons:
A - The difficulty in supporting new countries, when each
new plug design requires new tooling. With an inline
design, only the plug at the end of the AC cable has to
change.
B - The wall wart

Everything you said seems good to me, and I agree.
