Both he new Surface Book with Performance Base and the Surface Dial accessory are now officially on sale. While both new Surface products were previously available for pre-order, they're now officially available to buy at the Microsoft Store and Best Buy.

Surface Book with Performance Base and Surface Dial now on sale

To recap, the Surface Book with Performance Base is meant to offer an extra boost in performance over the original Surface Book lineup introduced in 2015. The rather expensive model packs not only increased battery life, but also some extra graphical power thanks to an upgraded GPU. We came away pretty impressed in our review of the latest addition to the Surface Book lineup, but it is on the expensive side of things.

As an aside, Microsoft notes that it has also extended its trade-in offer for current Mac users through November 23 — just in case you were thinking of trading up.

As for the Surface Dial, the new accessory allows some pretty unique interactions with apps that support it, as we've already seen. And while it's best paired with the upcoming Surface Studio, which will allow you to use the Dial directly on its screen, the Surface Dial can pair up with any Windows PC. At the moment, the Microsoft Store is sold out of its Surface Dial stock, but you can still order from Best Buy or pre-order from the Microsoft Store for delivery "later this year."
