An update to the brilliantly priced & popular Zenfone series, Zenfone 2 features a 5.5-inch 1080p display, 64-bit quad core Intel Atom processor, 3,000mAh battery & a neat brushed aluminium finish. The Zoom will interest photo buffs: it has a 13MP rear camera with 3x optical zoom (internal mechanism) and optical image stabilisation.
