The Z10 is a fully touchscreen BB10 device sporting modern specs, with cool patterned soft-touch material on the back. The screen is 4.2" LCD with 1280 x 768 pixels, making for a pixel density of 356 pixels per inch. A 1.5 GHz dual-core processor and 2 GB of RAM are the power under the hood, and there are 16 GB of internal storage, as well as the all-important microSD card slot. You will need all the RAM, because BB10 is a true multitasking system, like Android, so everything remains how you left it, or moves on under the hood, but is available at all times.
