IPv6 anyone? People must start to understand that "Because this is the way it is" is a valid, actually extremely valid, answer to any question like "Why don't we just switch technology A with technology B?"

Despite all the shortcomings of the old technology, and the advantages of the new one, inertia _is_ a factor, and you must accept that most users will simply even refuse to acknowledge the problem you want to describe.

For you your solution to get any traction, it must deliver value right now, in the current ecosystem. Otherwise, it's doomed to fail by being ignored over and over.

I'd say that usually it's not about the balance of advantages but the balance of pain. You go through the pains of switching to a new and unfamiliar solution if your current solution is giving you even more pain.

If you don't feel much pain, you can and should stay with your current solution. If it's not broken, or not broken badly enough, don't fix it by radical surgery.
