There is one good thing about a cord. It will keep certain items in place. Unlike my cell and cordless phones, I will always know where my corded (yes they still exist) landline phone is. But letting go a little control in return for saving on energy costs as well as using an eco-friendly product is well worth it.
The Greenman lamp, which is made from eco-friendly bio-plastic corn and trimmed off with bamboo, is a fun and modern looking lamp that's cordless. It's solar powered so you power the lamp by flipping it over during the day. This has been a very tricky item to chase down a place to buy it. While I couldn't find a US distributor, I did find one that ships internationally. $54 (approx) @ MadeInDesign.Co.Uk
