[OLPC-AU] OLPC-AU Digest, Vol 4, Issue 4

[Sridhar Dhanapalan]

It's still early days, so we don't have accurate numbers. I've heard
talk of a 4x increase in CPU performance, and a dramatic decrease in
power consumption.

This work goes some way towards the XO-3, but to quote Ed McNierney
(my counterpart at OLPC), "An OLPC-3 tablet is a long way away and
it's not really useful to discuss/speculate on it now."

Right now, the XO-1.75 is in an early development phase, so a lot of
balls are still in the air. There's a lot of interesting discussion on
the devel list:
