Motorola's Droid 4 is touted by the company as the thinnest and most powerful 4G LTE QWERTY smartphone ever and was announced at the Consumer Electronics Show (CES) in January. The phone is powered by a dual-core 1.2GHz processor and has edge-lit keys for fast and precise typing even in the dark. The handset comes with a number of accessories, such as Lapdocks of varying sizes (with built-in webcams and Ethernet connectivity options) and vehicle navigation mounts.
Rivals Samsung, however, will be loathe to lose their position as the principal challenger to Apple's dominant iPhones and will be hoping the recently launched Galaxy S3 - the long awaited successor to the best-selling Galaxy S2 - will be enough to hold off any and all challengers while dealing Apple a death blow.
