Reviews Word on the street

BlackBerry Z10  vs Bold 9900 

That said, with proper lighting, the BlackBerry Z10 captures sharp and colorful shots and fairly smooth 1080p video.
BlackBerry Z10

Similar to its contemporaries, the Z10 is armed with all of the connectivity arsenal we’d expect to find nowadays – such as aGPS, Bluetooth 4.0, 5GHz 802.11 a/b/g/n Wi-Fi, mobile hotspot functionality, and NFC.
BlackBerry Z10

Load speeds are pretty similar over Wi-Fi, but a strong connection can see a second or so knocked off the desktop sites.
