Samsung Focus S
PROS: Windows Phone 7.5, AMOLED screen, excellent camera, tethering support
CONS: A bit large for some users, not really 4G
RATING: Four out of five stars
RECOMMENDATION: Samsung's flagship device for Windows Phone 7.5 is a winner, with a large but thin and light form factor, a gorgeous 4.3-inch Super AMOLED Plus display, 16 GB of storage, and a speedy 1.4 GHz processor. It sports both front- and back-facing cameras, and the primary camera is unexpectedly excellent, with 8 megapixels of resolution and true-to-life colors. Brings the best-in-market mobile OS, Microsoft's Windows Phone 7.5, which includes Internet sharing (aka tethering) via AT&T's wireless network. Despite its airy lightness, it might be a bit big for some customers, and AT&T's claimed 4G speeds are a far cry from the real thing.

Samsung Focus Flash
PROS: Windows Phone 7.5, small form factor, tethering support, inexpensive
CONS: So-so camera and storage, not really 4G
RATING: Three out of five stars
RECOMMENDATION: While the Focus S is an obvious follow-up to last year's Focus, the Focus Flash is different. First, it costs just $50 with a new 2-year wireless contract. (The Focus S is a more standard $200.) Second, it comes in a small, light, and fun form factor, with tapered sides, a gorgeous but small 3.7-inch AMOLED screen, and in a curious first, a mechanical Start button surrounded by capacitive Back and Search buttons. It stumbles a bit in the specs, though the form factor will attract those already on the fence about large-sized smart phones. Aside from its powerful 1.4 GHz processor, it offers a lackluster 8GB of storage, a middling 5 megapixel camera, and AT&T's not-really-4G wireless network support. But it’s so cute, none of that might matter.
