Unfortunately, there have been some questions raised recently about whether bamboo is indeed greener than plastic. But there's no doubt that, just by virtue of it's natural look, it appears green. The good news is that Asus is looking at more than just its materials when trying to green its products. The innards of their new computers are labeled for easy repair and recycling and they're some of the first laptops that are truly upgradeable, instead of being semi-solid slabs that are all-but-impossible to upgrade and self-repair.
But the bamboo, it seems, is pretty much a symbolic statement. Though, I have to admit, it's a nice one.
