Oblivion had Npcs that rode horses, there are many places where guards can be found patrolling while on horseback, they can simpliy do the same with skyrim and give followers the ability to be ordered on horseback. In large scale battles some soilders are on horseback making battles much more interesting and offering more combat capabilites.
