Google's original Pixelbook was an odd device, a $1000 premium Chromebook, standing out among a crowd of ultra-inexpensive Chrome OS devices. But despite the price, it attracted diehard fans with its bold design and powerful performance. The Pixelbook Go is an attempt at a follow-up for the mainstream. It's similarly high-performing but with a friendlier aesthetic. At $650, though, it's still a premium device in the world of Chrome OS, and it faces stiff competition.
