So Acer's new Aspire 3811TZ and Aspire 3811TZG may not be puke-green like Sony's VAIO W Eco
, but that doesn't mean they aren't some of the greenest -- as in eco-friendly -- laptops out there. Part of the company's thin-and-light Timeline series, the two 13.3-inch laptops have been named by Greenpeace as being completely free of those bad-for-the-environment materials, including PVC (polyvinyl chloride) and BFR (brominated flame retardants). Powered by Intel ULV Core 2 Duo CPUs, they are more power-efficient than most and last longer on a charge. There doesn't seem to be an official statement from Acer on availability and price on these models, but we assume like the rest of the Timeline bunch there will be models both north and south of a grand.
