Indeed, and I think you can probably measure that in decades rather than years !
Simple example - Windows XP "should" be dead, but it's not. There are still a lot of XP machines still in use (we have one in the house) on the basis that "it still works, why fix it ?"
My Mum still uses an old eMac running (IIRC) OS X 10.5 - on the basis that she knows how to drive it, and switching her to something newer will take "a bit of learning time" which is hard for someone her age and state of forgetfulness. I do have a newer computer for her, but it's finding time to sit down and explain all the differences - so far in preparation, she's been switched from Eudora to Apple Mail so that's one big change dealt with.

So yes, just wishing for IPv4 to go away in a few years because "everything will support IPv6" is just wishful thinking. No ISP is going to do something that's going to break a proportion of their customers' setups - just the helpdesk time (explaining that it's time for an upgrade) would cost them a fortune.
