The latest in Acer's long lineup of Chromebooks is the company's first convertible running Google's OS. The Chromebook R 11, due next month for $299, features an 11-inch, "HD" (1366 x 768) display, aluminum top frame, and an Intel Celeron chipset. It's 19.2 mm thin, weighs under 1.25 kg, and also features 802.11ac Wi-Fi and a USB 3.0 port. Like similar convertibles from brands like Asus, the Chromebook R 11 starts out in your traditional laptop mode but can also be flipped around and reoriented in different styles for watching movies or playing games. Acer is promising that the device's hinge is very durable and can stand up to extensive movement for as long as you own the thing. Is it a smarter buy than the Chromebook Flip? We'll need to wait until we've used one extensively ourselves before making that call, but competition's always nice.
