After all Linus Torvalds got his Nexus 7. Although he has absolutely nothing to report. He updated his phone immediately upon getting it.
Linus spent all initial time just updating the one-time passwords he has for all his toys and browser sync etc. However he is sure that there is some smart way to sync two different phones with google authenticator. It’s somewhere in the settings, He bets but hasn’t got yet. So the “obvious” way to update 2-step verification was to disable and re-enable it, which seems to invalidate all old authentication tokens.
He kept his experience open to world since he ordered it. That is a very good thing about him and may be to nexus 7 also. Wait for more of Linus Experiences about Nexus 7.
