At a conference we attended recently, one of the speakers showed a picture of several smartphones on a table side by side -- their screens black -- and asked the audience to identify which was which. They couldn't of course, and that was the point. Without software, one phone looks like the next. Such is the case with BlackBerry Z10 and iPhone 5. Were it not for the brand name emblazoned in silver across its front, the BlackBerry might easily pass for any of a number of today's smartphones.
The latest devices from Apple and BlackBerry are quite similar physically. The Z10 measures 5.1 x 2.6 x 0.35 inches, and the iPhone 5 stretches 4.9 x 2.3 x 0.30 inches. The BlackBerry weighs 4.78 ounces to iPhone 5's 3.95 ounces. Both are encased in metal and covered on the front by glass from edge to edge and top to bottom. Both achieve superb thinness by combining protective glass and touch sensitivity on a single layer atop the LCD.
