Hi Chris,

Nobody in the hardware industry publishes numbers doing the kinds of
active power management techniques you use like suspend and keep the
image in DCON - aside from maybe ebook readers. OLPC is up against
crap stuff like the Classmate which don't have anything like that but
can have a similar usage to common laptops. To avoid further scrutiny
from the media (like:
http://news.cnet.com/8301-13512_3-9766574-23.html ), it would probably
be better to forget the whole suspend techniques all at once.
Maybe it would be better to measure and quote a regular usage time,
which would be +- 3 hours on an XO-1 and 8 hours on ebook mode?

Best regards,

Tiago Marques
