If you're just putting around town, then you don't need to do it.
If you're actually using the turbo (extended highway drive or hauling ass) and you shut the motor off right when your done, then the oil that "bathes" the bearing stops circulating so it doesn't cool off the bearing so it cooks.
I know Audi turbos and Mazda turbos both have statements in the owners manual about not just shutting down the car after spirited or highway drives.
