Garbage Collectors solve some really hard problems in regards to memory 
management.

Some high performance data structures require it for memory reclamation 
and there is no alternative to it.

It is a very good base line for memory management when you do not care 
about its life time.

The more I have studied memory allocators & management strategies the 
more I wish I could go back to just relying on the GC and being naive. 
They really are amazing for most programs.

And in case anyone is interested, a book recommendation:
