I finally read through the Ars Technica review, and I like that they're calling Google out on things.
I'm not seeing enough reviews calling out the gesture navigation. Ars Technica's review does so nicely:
Gesture navigation takes Android's normal "Back," "Home," and "Recent Apps" button layout and just removes the Recent Apps button, making the whole bar look lopsided. The home button, which is normally a circle, changes to a pill shape, and now you can swipe up on it to open the Recent Apps interface. A swipe left on the pill will switch to the previous app, and a swipe right on the pill doesn't do anything at all. That's right—there's no gesture for "Back." The back button is still here and just awkwardly hangs out to the left of the home button whenever you are in an app.
Recent apps is also really clunky. Swiping up on the home pill opens Recent Apps, but it alsoopens the app drawer if you keep going. So, usually you open Recent Apps and then half-open the app drawer, which slides back down the screen after it realizes you don't want to open it. Putting the app drawer on the Recent Apps screen was supposed to be a benefit, letting you open the app drawer from anywhere. But since this is the only way to open the app drawer now, it's just a lot harder to get to. With normal navigation, the app drawer was just a swipe away on the home screen. Now you need two swipes, or one unreasonably long swipe that covers, like, 75 percent of the phone screen.
There's also a scrubbing gesture for Recent Apps, which you can access by swiping right on the home button and then keeping your finger down and moving left and right. This will rocketthrough the recent apps list and open whichever app you stop on. I've never found a use for it, since it's really finicky and hard to control.
This is spot on. Gesture navigation on Android is a half-baked, unintuitive mess. And Google needs to know this. It broke the app drawer, the scrubbing feature is difficult as hell to control and be accurate with (that is to say, it's useless), and the gestures don't do anything to save screen space.
I don't believe the Verge review, for example, even mentions gestures in the write-up. How can they not talk about the primary navigation interface of the OS?
