As part of wider Vaio launches at CES, Sony has unveiled what it is angling as an eco opton for those that want to compute on the go.

As well as being a bit of a mouthful, the 10.1-inch Sony Vaio W series "Eco Edition" mini notebook claims a 10% reduction in CO2 emissions during production compared with previous W Series models.

This is achieved, Sony says, through use of recycled plastics during manufacture. In addition Sony highlights the paper-saving e-manual, the energy efficient Atom processor (the N450), the LED backlight display and the fact the netbook is shipped in a carry bag, rather than cardboard.

Specs include Windows 7 Starter Edition, Bluetooth, webcam, Wi-Fi, 1GB of RAM, a 250GB hard disk drive and up to 8.5 hours battery life.

Looks-wise, as you can see from the hands-on pics we grabbed out at CES, the new W series effort gets a white finish, a green palm rest and patterned touch pad.

The new VAIO W series is due to be available from February 2010, no pricing revealed.
