I really have to agree with tanstaafl. The "purists" are the same people who became upset when Porsche started building water-cooled 911 engines (i.e., "the 993 was the last `real' Porsche") or who couldn't stomach the thought of something as pedestrian as the Porsche 944.
For somebody who's in the market for an insanely overpowered sportscar and doesn't mind spending $120K, there are very few choices and Porsche is, far and away, one of the best in terms of just about anything you can measure. As long as that market continues to exist and Porsche continues to serve it, then who's to complain? Anybody who buys cars as an investment or as an ego-enhancement device is only setting themselves up for disappointment.
