How many have NOT changed IMS bearing on their 1997-2000 Boxster?

I have a 2000 Boxster 2.7 (therefore unsure if double or single row bearing) with about 56,000 miles (92 Km) and the original bearing. I will change it, but not until the clutch needs replacing. Initially I was worried after reading of the various IMS bearing failures, but have decided to enjoy the car, change the oil every 4000 miles, check the filter for flilings and debris (next one is due in the next couple of weeks). Oh, and I have purchased a magnetic drain plug.
