The videos are fairly bare-bones, and you probably know what to expect from them. They each give the basic breakdown of key specs for each device, while showing the devices floating and spinning through space. A couple items to note in the Nexus 6 video are the textured power button, just like the new Moto X, and the Motorola logo on the back, which unlike the new Moto X is part of the back plate, rather than a separate piece. The profile of the phone also makes it look like it doesn't taper down at the edges quite as much as the Moto X.
With the Nexus 9, we're definitely digging the color options, and it is pretty cool to see the keyboard cover in motion. We'd like to see more on how adjustable the angle will be though, because it does appear to be somewhat limited. What do you guys think?
