For the price, it has imperfections, but if you set aside price it is a very good tablet. I like the size and form factor, and battery life, fast charge times given its battery life, good build quality, intelligent keyboard integration, and product stability.
I'd have preferred it was either a Chromebook or Nexus for the Devs, this is a Frankentablet which will have the problems of poor custom ROM and kernels for its life. I compare to say my Nexus 7 which is getting via Dev community frequent updates due to its vast popularity. Even my Nexus 4 phone I've had for 4 years I got a replacement battery for $9 and it is on May 1st MM AOSP and still useful comparatively as the day it was born. I doubt we'll see the Pixel C have such longevity.
This is a sufficiently good tablet I'm planning trips as this my only computer, leaving larger Chromebook and laptop at home, the keyboard integration is very good.
