[Sugar-devel] XO Infinity?

Thanks for your input.
My perspective is somewhat limited. I am looking at a deployment where
(a) internet access is unavailable or limited in capacity so that online
browsing by the laptop is not feasible, (b) a school server is available
to provide access to educational resources beyond what can be stored on
1-4GB of local storage, (c) institutional staff control access to the
laptops (users taking them home, a rare exception), and (d) all laptops
on the local school server network should, in so far as possible, behave
in the same way. This last is increasingly difficult: the XO-1 does not
have enough storage for Libre Office, the ARM based XOs do not execute
many of the Sugar activities with binary components (e.g. GCompris), the
move to support touch-screen has apparently put the XO-1 at software
end-of-life (while the XO-1 probably represents 80+% of the XO laptops
in current use).
Someone who comes to us with hopes to deploy the XO to a community
school, library, or orphanage has limited opportunities to acquire XO
There is surprisingly limited useful advice on things to consider in
planning such a deployment: solar or grid power, battery charging,
capacity of routers to support concurrent access to the school server,
good performance studies on the load placed on the school server by
40-100 XOs connected concurrently, how well sharing works with (or
without) ejabberd in an environment of 40+ laptops or what
teachers/staff need to know to support such a deployment. Strangely, a
much of this has been addressed in scattered emails and web pages (e.g
Richard Smith's contributions to understanding the electrical power
There is no clear consensus within the community on what the laptop
brings to the educational experience: collaborative learning using Sugar
activities, access to information (Wikipedia, Gutenberg books, Open
Street Maps), opportunity to learn to use a computer effectively,
opportunity to learn programming through Turtle Blocks, Scratch, Etoys,
Pippy, or View Source, and/or interactive support for meeting the
learning objectives of the school's curriculum. The 'commissioned'
studies on the impact of OLPC deployments invariably are focused on
observed improvements in student performance on standard tests - that,
at least, is the official consensus on what we are about.
