There's just no way around it; the Lumia 920 is beefy. Its measurements of 5.1 by 2.8 by 0.4 inches make the iPhone 5 appear comparatively Lilliputian at 4.9 by 2.3 by 0.3 inches. And the iPhone advantage translates to weight as well. The Cupertino-killer tips the scale at 3.95 ounces, while the Lumia 920 breaks the scale at 6.53 ounces.
Both phones are attractive. The Lumia 920 has a curvy polycarbonate unibody that's pleasing to the eye. Nokia also has taken to shipping its Windows Phone in a variety of colors. There's a lacquered cherry red that recalls a 1950's Cadillac, the cyan variant that popularized the Lumia 900, the gloss yellow looks a bit like an 80s-era Lamborghini Countach and there are more staid black and white as well. The iPhone 5's two-tone schemes that wax between dark and light variants are just as classy as the Lumia's paint jobs are eye-catching.
