What do you plan to use it for?
Overall, it's a great device, but if you have good desktop for gaming (which I think you do, right?) it might be worth it to just get a Surface Pro 4 instead. It's even more portable, and and can be laptop or tablet, like the book. Personally, I would go for the Pro 4 instead of the Book, but either one would be great if you really can afford either.
