Getwithgreen has a really helpful article on facts you should know about bamboo before you buy it, like, bamboo is actually harder than oak floors, and if the subfloor isn’t cured it can fade. Also some other good info,  including:

• Do you live in an arid region?  Because bamboo is used to high humidity, you will need to be sure it is properly finished and sealed to assure its durability.  The less expensive bamboo flooring may not offer the moisture resistant finishing.
• Strand Bamboo flooring is a third pattern, created as the bamboo is mashed up and bound.  It is much denser than either the Vertical or Horizontal grains and said to be nearly indestructible.
