As you probably already know, Sony made the Xperia Z and ZL official yesterday at CES. David got to spend some hands-on time with both handsets, and shared his initial thoughts on the duo right here. If that wasn't good enough for you, though, then perhaps the metric ton of videos Sony just uploaded will get the job done.
Without further ado, I present to you: slews and slews and slews of videos about the Xperia Z and ZL. Enjoy.
