18. Samsung Focus Flash
Carrier/Price: AT&T, $1
Last year's Samsung Focus ushered in the WP7 mobile platform and became its best-selling handset to date. Now Samsung is leading the Microsoft Windows Phone 7 brigadge with the speedy and inexpensive Focus Flash. You typically wouldn't expect much horsepower from a smartphone originally retailed at $50, but that's far from the case here as the Flash sports a strong 1.4GHz CPU. The manufacturer's beautiful Super AMOLED screen dishes out amazingly crisp visuals and plays 720p/1080p videos fluidly in full screen. Top it off with good voice quality and HSPA+ network support, the Focus Flash gives you near-premium specs at an incredible value.
