Best Buy is selling the Microsoft Surface Go (128GB) for $399 (opens in new tab), or $150 off. Better yet, you can get the Surface Go with the Type Cover keyboard for $499 (opens in new tab) after a huge $180 discount. These are the lowest prices we’ve seen on this particular Surface Go model, which is the upgraded configuration with 8GB of RAM and 128GB of storage. In our Surface Go review, we praised the tablet for its stunning 10-inch display, comfortable backlit keyboard and decent performance. All of those features are contained within a premium metal chassis that has an IR camera for speedy facial recognition login via Windows Hello. The Surface Go is already a great value at its original retail price for anyone who wants an ultraportable device for streaming content or getting basic work done. This new sales price makes the Surface Go one of the best purchases available on a tablet or laptop. That said, the Surface Go isn’t the most powerful device, and its design is looking a bit dated. And as portable as this slate is, its below-average battery life (6:06) will prevent you from using it on long, international flights. We also expect Microsoft to announce a Surface Go 2 at some point this year, although it’s not clear when. Regardless, if you want an affordable Windows tablet that can be converted into a laptop via a detachable keyboard, then it doesn’t get much better than this.
