Mirror, mirror, on the wall, who's the greenest laptop of them all?

The new ThinkPad L Series laptops from Lenovo, that's who.

The Chinese PC maker, which has a world headquarters in Morrisville that employs more than 1,500, announced today that its new L512 laptop contains 18 percent post-consumer content -- used IT equipment and recycled office water jugs -- more than any other laptop.

Each of the new L Series laptops use the equivalent of 10 recycled plastic water bottles, according to Lenovo.

"Despite the typical solid specs that we expect from a ThinkPad," notes the online Digital Trends newsletter, "the models will live or die on whether the green factor can truly sway consumers into not just going green, but buying green. If it proves to be a sustainable model that attracts users, Lenovo may have opened a door to a new eco-based market. After all, it worked wonders for Toyota with the Prius."

And, by the way, today's announcement precedes Earth Day by a mere two days.

The ThinkPad L412 and L512 will be available in mid-May and start at $649. Lenovo touts them as incorporating "the latest Intel processing technologies, military tough durability and strong Web conferencing feature in an affordable laptop."
