But to be fair, everyone gets a cheap phone every two years, so what's 1% today will be 100% in two years. Remember, the G1 is three-ish years old, and it's mostly gone now. The Nexus One was released on January 5, 2010, and so only the earliest of early adopters (with a standard contract) are just now gaining the ability to upgrade.

Two years is a long time, but if IE 6 went away after two years, we wouldn't even remember that it was once a thing :)
