Pros
Pro Optional keyboard accessory
The keyboard can also act as a tablet stand, and doubles as a screen protector when not in use. It connects through bluetooth, and attaches to the tablet via magnets. When you aren't using it, just place it on the screen (keys facing in) and magnets will hold it in place, protecting the tablet's screen. While it's closed like this, the tablet will wirelessly charge the keyboard, meaning you don't ever have to worry about the keyboard's battery (it should last up to 3 months even if you never let it charge). It's a bit pricey at $150 extra on top of the tablet, but it's an option you have.
Pro Clean, quickly updated software
Pixel C runs software made entirely by Google - known as Stock Android. This software performs quick, and doesn't include any bloatware. It is also promised to be one of the first to get Android N this fall, as well as the next release next year (and very likely one more major update before support ends).
Cons
Con New charging port
Old micro USB cables will not work with this device, meaning if you lose or break your cable you will need to buy a new one instead of using an old cable you had lying around. If you need to top up your phone away from home, it will be much harder to find a suitable cable initially.
