Considered neither light nor heavy, the BlackBerry Z10 smartphone does not weigh down the multi-tasking of busy users throughout the day. Unlock the phone by an upward, uncomplicated swipe requiring a concentrated effort, so it does not occur accidentally. The 720x1280 pixel resolution keeps viewing sharp, colorful, and bright without seeming stark. The intuitive interface has three home screens to include a multi-tasking pane, hub, and apps. A flashing red light placed strategically in the upper right portion of the screen alerts you to incoming messages. The predictive text feature displays a list of words to choose from and fills in the letters, as you type a message. Noteworthy functions include an impressive browsing speed and zooming feature to read web pages.
