I voted yes but my case was that a PPI found evidence of an impending IMS failure (leak, and metal in oil filter) and it was replaced by the seller with the LNE upgrade, along with an RMS upgrade. So, the real poll answer is "Not failed yet but evidence of impending failure requiring replacement". Definitely it is not a "No Issues" answer.

2003 996 C4S, currently 52,500 miles.
No issues but I pro-actively replaced mine with LNE at about 51k miles. My Indy said there was a leak coming from the area which I witnessed. When removed, the bearing seemed solid and fine.

90k miles. Just replaced with LN engineering.
Dual row...
The factory original IMS bearing showed no wear, or play. Still gives a warm and fuzzy knowing it's replaced though.

Bought '03 Targa with 83,000 miles in the summer of 2012 with a 3 year power train warranty. Indy inspected original bearing, and it is fine, but I'll likely put in the LN bearing before my warranty expires.

In order to inspect an IMS bearing, you would have to verify the bearing was still full of grease. The only way to do that is to remove the bearings grease seals which would destroy the bearing.
Thus, if your "Indy" inspected the bearing, he destroyed it then put it back in. It is good you have insurance.

Wow. You mean your "Indy" removed the bearing, inspected it, then re installed the old bearing?

Yikes, then I probably misunderstood him. The shop that I go to is Porsche specific, and it has been around for over 30 years, and I feel good about their work. He probably just meant that there were no signs of IMS issues, like bearing particles or whatever. Thanks for the clarification.
If your Indy did not cut the filter up and examine it, then all you got was a verification the bearing had not failed because the engine still runs. If this is all you got, I would not assume the bearing was "fine".
Possibly a cam timing analysis on a program like Durametric could provide an indication of the health of the bearing by indication how close cam timing was. But I have not heard of anyone analyzing a bearing that way.
But you have insurance, and that makes it irrelevant.

At 40K with a 2003, and a needed clutch change I replaced my IMS and now have the comfort of mind that it will not implode. The original IMS was flawless and is now an expensive paperweight on my desk.

So, what are the odds of getting one with a bad bearing? 100% 50/50? I am new as well but don't roll your eyes. This is a great form. I have always worked on my cars because I had to buy beaters. Never worked on a porsche. I'm not scared of basic stuff and some more technical repairs....but the IMS scares the crap out of me. I am looking at a 1999 911 Carrera 4. 24 service records and 1 owner. Previous owner replaced water pump, fuel pump, rear seals, window regulators, crank shaft position sensor in Nov of 2012. All done by the dealer that I talked to my self yesterday. But have not replaced the IMS.
