I feel as though Google has always made these type of devices to showcase their software, and it has made other manufacturers step up their game with higher end units and design.
The PB is an amazing device that (I feel) has made Chrome OS more "mainstream" and a viable option for people considering either a Surface Pro or an iPad Pro. Personally, I reach for the PB 95% of the time over my Surface Pro.
Now that I have added a Pixel Slate to the mix, (yes; tech junkie, I know) I find that the PB is getting less use around the house, but is still the "go to" device for my business needs.
