Comparing "valid" bugs
If you compare the rate of resolutions for just valid bugs (meaning reproducable, not by design, and not duplicate) submitted by customers versus the internally submitted ones, the fix rate is almost the same and we're "Won't Fix"ing fewer customer issues.
Bugs | Internal | MSDN PFC | Suggestions | Internal | MSDN PFC | |
Fixed | 79% | 78% | Fixed | 23% | 19% | |
Won't Fix | 14% | 12% | Won't Fix | 44% | 30% | |
Postponed | 7% | 10% | Postponed | 33% | 51% |
