Nanonote in schools

It was very interesting to follow the recent post about the Nanonote
sales and how it can be used. Open-source hardware is definitely a
great idea and has a future. However, end users normally choose
functions over freedom and it's important for us to focus on
developing the functionalities that sell.
I just wanted to highlight that it has a great potential to use in
schools especially in a developing country like Nepal if we could
develop a custom software with the digital content like E-Paath
(http://www.olenepal.org/e_paath.html). It is a collection of digital
education materials prepared by OLE Nepal (http://www.olenepal.org/).
This freely available content is relevant and localized to Nepal's
schools curriculum that can be downloaded and used in XO laptops or
Windows PC or used online
(http://www.pustakalaya.org/external-content/static/epaath/epaath/).
Last summer I used five Nanonote with Jlime with five English teachers
in five different secondary schools of Nepal. I just had audio video
content and teachers used it in classroom mainly for listening
activities with a cheap chinese rechargeable speaker. Due to lack of
infrastructure (electricity, internet, affordable devices etc), such a
solution with offline content will also be very useful. But I'm sure
developing software to facilitate teaching/learning activities will be
challenging and I wonder how our community could support in that
matter.
In my University of West london, we also used it to support teaching
embedded programming where students were required to complete
assignments which required developing a command-line application that
was capable of communicating structured binary data across a TCP/IP
network and suitable for deployment on a Linux based embedded device
such as Nanonote or Freerunner. Students also found useful for
audio/video content but nobody really use it to read normal size pdf
mainly due to small screen size.
