Samsung ATIV S
Samsung's super-slim Windows Phone 8 device, the ATIV S, is a looker thanks to its chic design and metallic bezel. Its 4.8", Super AMOLED display is meant to view HD media in all its glory. A 1.5GHz dual-core processor provides the power you need to seamlessly perform work and personal tasks. Unfortunately, the ATIV S doesn't support LTE.
Availability: No release date is available, but the ATIV S's lack of LTE suggests T-Mobile may be the only U.S. carrier to offer the device unless an LTE version is released.
Notable Features iPhone 5 Lacks: New Windows Phone 8 OS; expandable storage via microSD card; and NFC.
