You forgot the one where you could use them as two 9bit/55bit fixed point numbers representing latitude and longitude and have your IP address identify where you are to within a couple of microns :-).
And computers have gotten so fast and memory so large and storage so cheap that nobody cares. I get it. During the IPV6 discussions at IETF people kept saying "but 64 bits is just twice as big as our current space, we'll run out in no time" and I kept saying "No its 4 billion times bigger". It is water under the bridge.
At some point I'm going to sit down and reason out the cost of 128 versus 64 bits (which is the inverse of 'why they are great' but more 'why they aren't great') but since I never expect that I'll get a chance to design network protocols at that level again its really just a hobby for me.
