Turbo vs. Non-Turbo

I am considering buying an 88 911 Turbo. The car is in mint condition with low miles. Is it true that turbo engines die a faster death or is it that they are usually driven harder?? Are the costs to maintain also higher. I currently own a 82 SC and am trying to get a feel for what I am in for (other than faster acceleration!!). Anybody have any thoughts on the Turbos???
