Update: The manual has now been updated with the URL for the gOS image.
As promised, kogan have published a user manual for the kogan agora netbook on their netbook support page:
http://www.kogan.com.au/media/uploads/Kogan-Agora-Netbook-User-Manual.pdf
It does however have a few gaps. I was keen to see the factory restore instructions, however whilst is says “Download the kogan gOS.iso image file from this link”, there does not appear to be a link! Hopefully this will be resolved soon…
