The BlackBerry Q10 boasts a superb physical keyboard, the latest BlackBerry OS (version 10.1), smooth performance, and long battery life. A deep and luscious all-black, the slablike Q10 has an appearance that's all buttoned up and ready for business. If you've used a BlackBerry Bold or even an ancient Curve handset, the BlackBerry Q10 will feel like an old and familiar friend. The Q10 is cut in the same classic flat shape with softly rounded edges that graced other BlackBerrys. Above the 3.1-inch screen sits a large circular notification light that flashes an angry red to compel you to check your messages. Below the display is the phone's large keyboard, right where you expect it.
