Perhaps somewhere by OLPC? Or at individual deployments?

Sorry I was unclear. The point I was trying to make is that until the XO-4,
we had not yet achieved the goal of < 5W power consumption. The XO-1 was a
huge step forward in terms of "green" computing, but the XO-4 was the
machine we aspired to build in 2006-7. Further, while the phone industry
has taken low-power as a serious goal, few laptop manufactures have made
much progress on this front. Every time I refresh my Thinkpad, it seems to
be more power hungry rather than less power hungry. Something wrong there.
