With a 720 x 720 Super AMOLED 3.1-inch display, the Q10's screen is slightly larger than its touch-hybrid predecessor, the Bold 9930, and sports a much tighter
pixel density of 328ppi (BlackBerry claims the display is 360ppi, which doesn't jibe with our math). The 1.5GHz dual-core CPU and 2GB of RAM keep the device humming along quite smoothly. It reacted almost instantaneously to input with no hiccups.
