I completely agree and was just about to make a post comparing logger/debugger to bike/car. I guess we think alike!

There are also quite a few bugs where you need some kind of debugger in order to track down the bug. I am thinking crash dumps (using WinDbg for example) as well as memory corruption in C/C++. Being able to set a breakpoint when a certain address in memory changes has basically reduced most memory corruption bugs from a week-long nightmare to more of an inconvenience for me (mind you, it's still my least favourite type of bug to investigate).
