Here’s Google’s full description of the Nexus 10, touting it as “the first truly shareable tablet”: Nexus 10: Powerful and shareable Nexus 10 is the ultimate tablet for watching movies or reading magazines. We wanted to build a premium entertainment device, so we partnered with Samsung to do just that. Nexus 10 is the highest resolution tablet on the planet at 2560-by-1600 (300ppi), that’s over 4 million pixels right in your hands. It comes with a powerful battery that will get you up to nine hours of video playback and more than 500 hours of standby time. With a set of front-facing stereo speakers, you can watch movies right from your Nexus 10 and they simply sound awesome. But what makes Nexus 10 unique is that it’s the first truly shareable tablet. With Android 4.2, you can add multiple users and switch between them instantly right from the lockscreen. We believe that everyone should have quick and easy access to their own stuff — email, apps, bookmarks, and more. That way, everyone can have their own home screens, their own music, and even their own high scores. As shown the teaser image and promo video below, the Nexus 10 is the largest of three products announced today by Google: the Nexus 4, 7 and 10. (via Google Announces Nexus 10)
The multi-users feature of Android 4.2 is something really interesting. Apple should consider doing something like this on their iOS devices, specifically the iPad which is a much more multi-users devices than an iPhone or an iPod touch.
