BLACKBERRY Z10

The BlackBerry Z10 heralds the rebirth of a fallen leader in the smartphone market. It's a clean break from the past with a big touchscreen and novel OS, but the same business mentality that made it the favorite of office dwellers around the world. Except, this time BlackBerry has also added a dash of fun.

BlackBerry's previous generation of touch-driven smartphones felt a lot like Nokia's early attempts to knock Symbian into shape for touchscreen. With the Z10, however, the company threw everything out and started fresh.

BlackBerry 10 that powers the phone is a modern operating system with a brand new gesture-based interface and support for powerful dual-core CPUs. If you think dual-core Krait is old news on Android, you'd be right, but the Z10 is closer to the iPhone in this regard - the OS has been optimized to run on very few devices (just one right now, one more on the way), allowing for maximum efficiency.

Then BlackBerry equipped the Z10 with a 4.2" WXGA screen - slightly bigger and sharper than the iPhone 5's retina display - but kept the package more compact than certain massive droids. Then came all the connectivity features, hardware ports and slots.
