Are you thinking hardwood, linoleum, pergo? We put in a pergo laminate floor in the master bedroom, and I like it there. Not sure how it would do in a main living area with pets, though--the hardwood in our main living area was put in before we bought the house, and I love it.

I tell you what else I love: I HAVE MORE ICON SPACE! Wow, I am still marveling about it.
