I agree. Apple does it really well, no doubt about it. This is because
they control both the software and hardware.

Google/Android ├žan not do it well enough, since the Android OS version
compatibility with the hardware is somewhat dictated by the hardware
manufacturer. This isn't always helpful. :-(

But they can actually push pretty well if they had some killer app. that everyone
used and could supply some update that nobody could live without on said
killer app.

Then you just need to flag said update as "requires Android version X" and
poof... All the pressure you need to get everyone running droid up to X.
(Including all the pressure needed to get consumers to push the device

      For ex, there are numerous android apps that are not supported
      on many android devices. :=(

They must not be very important to the bulk of the android users.

Anyway, this is why I think that dual-stack home networks (and UEs) will
be with us for a long time.

I don't doubt that dual-stack home networks will be with us for a long time.
What won't be with us for very long is routing IPv4 across service providers.
It can't. It will become far too expensive to do so. The economics aren't going
to work much past about 5 years, maybe 10 if we're really unlucky.

Like you, I would like to be optimistic about many v4-only apps and
v4-only devices becoming dual-stack sooner than later.

But knowing that a significant (50%+) of android devices may not support
IPv6 (just like my brand new Samsung Galaxy 7'' tablet (just bought over
the weekend) being v4-only) and may not be upgraded by their users to
right software, and that Skype etc. apps are out there, my optimism

The upgrade problem isn't that hard to solve. As soon as users want to use
something that doesn't work without the upgrade, the upgrades get

Apple does a great job of this...

Every time they release an iOS upgrade I really don't want, they manage to
also release an update to software that I do care about. That software
inherently requires me to accept the iOS upgrade.
