Valve are introducing another brilliant idea called SteamCloud. It will allow the company to store your user data online. This includes save games, keyboard configurations, preferences etc.

Valve today announced Steam Cloud, a free Steam system that will retain users' saved games and configuration files indefinitely.
Half-Life and Half-Life 2 will be the first games to support the service. User key mappings will also be saved in Counter-Strike, and Left 4 Dead will ship with the feature.
