Basic Information from Blizzard regarding Tauren:
The Tauren are huge, bestial creatures who live in the grassy, open barrens of central Kalimdor. They live to serve nature and maintain the balance between the wild things of the land and the restless spirit of the elements. Despite their enormous size and brute strength, the remarkably peaceful Tauren cultivate a quiet, tribal society. However, when roused by conflict, Tauren are implacable enemies who will use every ounce of their strength to smash their enemies under hoof. Under the leadership of their ancient chief, Cairne Bloodhoof, the Tauren allied themselves with the Orcs during the invasion of the Burning Legion. The two races have remained steadfast allies ever since. Like the Orcs, the Tauren struggle to retain their sense of tradition and noble identity.

The TenTonHammer take on Tauren
My first reaction at seeing a Tauren in action was to nearly wet myself. The Tauren are HUGE and probably the most immediately intimidating of all the races in WoW. While this intimidation can work to the advantage of the Tauren, it seems that sometimes it can cause issues when engaging with other players.
Tauren start in Redrock Mesa and can eventually move to their home of Thunder Bluff after sufficiently adventuring. From here the Tauren can access anywhere in the world if they wish.
