They say that imitation is the sincerest form of flattery. And in the tech world, imitation occurs frequently. Take, for instance, the Motorola Razr V3--a.k.a. the cell phone that swept the mobile world this year. It's a no-brainer that other manufacturers would scramble to mimic the popular slim design, and as expected, Samsung is the first to offer a Razr reproduction, with its MM-A900. Offered only by Sprint, the Samsung MM-A900 equals the Razr's thin profile but raises the bar with a couple of refinements and some extra features not found on the Motorola handset, including a 1.3-megapixel camera with a swiveling lens and a flash, an MP3 player, and support for Sprint's new 3G network.

Of course, Motorola is close on Samsung's heels with new models such as the Razr V3c for Verizon, but the MM-A900 is a strong effort nonetheless.Like the trendsetting Motorola Razr V3, the Samsung MM-A900 is all about a slim, sexy design. Fashioned in black, the MM-A900 is marginally bigger than the Motorola phone at 3.9 by 2.0 by 0.6 inches, and it weighs a bit more at 3.9 ounces, giving it a slightly more solid feel. Despite the added girth, however, the MM-A900 is still an incredibly thin phone that can slip into almost any pocket. Be aware, however, that like the Razr, it can be difficult to feel the phone's vibrate mode in your pocket.
