The Q10 is similar to the Bold 9900 in shape & size, but has a larger 3.1-inch super amoled touchscreen and improved keypad. The four-row keypad now has larger keys, a wider layout and feels more comfortable to type on. The display is fantastic but the 1:1 (square) aspect ratio sometimes ruins the video experience. Since most videos are 16:9, they run in a smaller frame on the phone. Performance is great — games and HD videos ran without any hitch even with multiple email and social networking accounts running in the background. It also shares the rear 8MP and front 2MP camera with the Z10. Like the Z10, the performance from the camera is fantastic — you get rich colours, sharp details and minimal noise. 

The Q10 has a 2,100mAh battery that easily lasted us over a day and half — impressive for a BlackBerry device. For those who love physical QWERTY keypads, the Q10 is the ultimate device. 

However at Rs 44,990 (850 USD), it's also insanely expensive. Because of the price, the Q10 has very stiff competition: the HTC One, Samsung's Galaxy S4 and the Apple iPhone 5.
