• Chuwi CoreBook Air Plus running Linux: Hardware Review - LinuxLinks

  The Chuwi CoreBook Air Plus has a price of $629 (that’s not an affiliate link). There’s a $50 early bird discount available which brings the price down to $579. And Chuwi is offering LinuxLinks readers a 13% discount on the purchase price. Use the discount code LinuxAirPlus at the checkout. With both discounts applied, the price is $547.23. For UK readers, this means the laptop costs around £400. There’s also a 14-inch model available (the Chuwi Corebook Air) at a lower price.
