NAT may be a good short term solution to the address depletion and scaling problems. This is because it requires very few changes and can be installed incrementally. NAT has several negative characteristics that make it inappropriate as a long term solution, and may make it inappropriate even as a short term solution. Only implementation and experimentation will determine its appropriateness.

Nothing. It fixes the myriad of horrible hacks that are required for ipv4 to somehow still hang on.

Of course companies are sad because transition costs money, even though as usual the open source community did most of the work for them.
