Hardwood Floors Or Ceramic Tile. Your Preference?

My wife and I will be installing new flooring in our house in the near future. We’re trying to decide the best route to take. We will probably put the house up for sale in about 5 years, so we want to consider resale value/attraction.
So, if you were buying a house, would you prefer real hardwood, ceramic tile, or a combination of the two, throughout the whole house (2800 sf)? We prefer to have hard floors in all of the rooms, but would you (as a buyer) prefer carpet in the bedrooms?
Thanks for any input.
