If you like gadgets that are earth-friendly, then why not get a keyboard made from wood? You don't get much more eco-friendly than bamboo.
This keyboard comes from Marubeni Infotec in Japan. It's cool because unlike other gadgets that just have a wood finish, or wooden accents, the whole thing is made from wood.
No word on pricing or availability on these, though I expect that you'll have to go to Japan to get one.
But does it need varnish? [via crave]
