Wait, this analogy is not very logical! The whole thing sort of falls apart as the old Nexus One phone was the very first to live here, followed by the Toshiba Thrive 10.1" tablet.
The middle one is my newest device. I got the Nexus 7 (2013) on Sunday, but it is already my most favourite. So, I guess I CAN go back to the original reference in one way. I can do this because the middle screen seems j-u-s-t right!
