Yes, it's *great* that this note is on that wiki page however I'm
mainly
concerned about the major public interfaces such as
http://one.laptop.org/map as well as Nicholas and Rodrigo constantly
refer to "2,100,000 children and teachers have XO laptops" when that
is
quite clearly not the case.
As Caryl will talk about OLPC at the Scale conference this week I
wanted
to use the opportunity to share what I feel are more realistic
figures;-)
Short of polling every deployment - which is done - on the distributed
versus locally warehoused number unless you also want to know the
number of xo's in repair status (how literal are you being about
"have"?); I'd reduce the number by 100-200k; approximately a month's
production and an equivalent number in transit whose time which can
take up to 8 weeks for land-locked countries. The upper-bound might
capture local inventories too.
so, about that rwanda number you are quoting...?
also curious about the classmate deployment figures you were
researching some time ago, what did you find?

The information below represents the number of XOs delivered,
shipped or ordered for each country or region. Not all XOs are
currently in schools."
That seems to be exactly what the wiki page is saying.

I agree with Walter. About two million. I don't have access
to the
internal figures.
See also 1,834,500 in a probably partial list of laptop orders:

http://wiki.laptop.org/go/Deployments
There are over 2.1 million XOs in the field as of January, 2011.
we update the wiki and the map every 4-8 weeks based on the actual
order and producation schedules
a mapping of many of those same deployments:
http://one.laptop.org/map
I still don't buy that 2.1 million figure. Ordered maybe, shipped by
Quanta possibly, but definitely not "in the hands of children and
teachers".
The data on http://one.laptop.org/map also adds up to about
1,800,000
with no significant omissions that I can find (definitely none
that add
up to 300,000) so I think this is pretty much the upper bound
right now.
Peru had 250,000 XOs in the field (with 40,000 more in a warehouse
in
Lima) as of late August 2010, I have a hard time believing that
since
then an additional 620,000 XO have actually been distributed.
The map and corresponding wiki pages also indicate that in Rwanda
110,000 XOs have been distributed when at least as of three weeks
ago
that number was actually closer to 15,000.
In the U.S. G1G1 numbers also seem to be included in the total
95,000 tally.
So overall my personal *guesstimate* at this point is that 1.5
million
is at the very best the *number of children and teachers with an XO*
with a more likely figure being somewhere in the area of 1.2
million.
I know others don't think these details matter, but as I explained
to
Robert back in Vienna exactly one year ago I believe getting these
numbers right is important considering how historically OLPC
hasn't been
too good in matching the numbers it has thrown around ($100
laptop, 1W
laptop, etc.)
Cheers,
Christoph
