solid bamboo is actually engineered in case there is some confusion. they use something like half inch pieces glued together.  lumber liquidators has a nice selection of colors too.  I took home some samples to compare to traditional solid (walnut), with my boxknife i was able to scratch both, the bamboo went straight down to bare wood, the traditional wood only scratched the finish but not down to bare wood.  from what I understand the finish is just not as high of quality as other prefinished wood? is that because its from china? 

One of the disadvantages of China bamboo flooring is that you will feel too cold in winter if you walk on it. Or just looking at the floor,you will feel too cold in winter.

My solid bamboo test sample (which was flat after it dried) is a nice rich brown color. Finish - I'm sure it depends on exactly what it was finished with - the engineered hardwood sample (by a well known US brand name) I tested bubbled when the finish got wet. The bamboo finish was fine.

FYI. I recently watched an talk given by Steven Milloy author of the book Green Hell. Hey – I like to see what all sides are saying! I didn't agree with much he had to say but was struck by one thing in particular. Steven spoke very knowledgeably about bamboo.

I am aware that tobacco and cotton are very bad for the soil they are grown on. Steven said that bamboo is right up there with tobacco and cotton. He said vast tracts of land in China and elsewhere are being devastated by growing bamboo for the silly eco freaks thinking they are going “green”!

Also I attended a talk by a guy (I can't remember his name) that was heavy into green commercial construction. He cautioned that bamboo had proven to be a disaster anywhere he had seen it used. It did not wear well at all. His suggestion was put it on a wall if you must use it – not a floor.

Anyone know any contrary facts about Mr. Milloy's theory?

Bamboo is in the middle of hardness values for hardwood floors - so I want to see proof for it being anything other than average in wear. Better yet, if you are considering any flooring, get some samples and test them. And little pressing, pounding, scratching, soaking and sanding and you would have much better data than any speculation.
