some first impressions... this thing boots up so fast. practically instantly. Also, to turn it on and off, it's just a quick tap. No long press of anything. It's very tactile in that every button has a shape and impression so you can use it blindly. You can get into recording much more quickly (tap a button) than a smartphone (load camera app, hit record). I know on my phone, I can instantly take a photo without loading an app but not so for a video.
You don't have to worry about how you hold the device or worry about accidentally stopping a recording like with a smartphone, especially a big screen smartphone that has the display go edge to edge with no bezel. As you record, there's a blinking red box outline around the screen so you're not just depending on a Rec symbol.
So a scenario that came up today... Now I'm not advocating this behavior but just listing it as an example of how quickly you can get to recording. There was a car accident on the freeway. Now with a smartphone, you have to load the camera app and hit the record button, both of which requires that you look at the phone. Both of which takes time where you can miss a big chunk. On the V10, you can instantly get into recording without looking. tap the power, tap the record and just aim. Even if you don't aim the camera correctly, because it's such a wide angle, you'll get the shot.
It's heavier than a phone. But it's more compact and easier to hold. There is a place where you can loop the camera strap to but it's at the bottom of the camera which is dumb because it means you have to pull the strap out of the way if you're using the kickstand. They should have put the loop near the top.
