For comparison, OLPC target weight is 1.5 kg.

The VAIO TR series were 3.1 lbs with an optical drive and a larger screen. I notice that the OLPC lacks an optical drive and that the battery on the OLPC seems to provide more energy. The Vaios seem to use LithiumIon as opposed to NiMH for the OLPC. So I guess that could account for the difference.
VAIO: 17WHr

The OLPC display is closer to something you'd accept on a PDA than a laptop, and it's accepted that it will come with some dead pixels. Its designer said that the kids it's intended for don't even have window glass in their classrooms and don't care about dead pixels, and of course that is a major factor in manufacturing yield. I doubt Intel's taking economies that severe. I thought lithium had more energy.Bruce

So the point presumably is that for similar Wh numbers the OLPC must have a lot more battery mass in it, which explains how the Vaio fits a lot more functionality into the same weight spec.
