Dual-slider phones like Sprint’s new Samsung Exclaim SPH-M550 may not be very common, but they’ve won their fair share of attention because they’re so peculiar. With both a standard alphanumeric keypad and a full QWERTY keyboard, they offer the best of both worlds. And it’s rather fun to figure out how they’re put together.

Similar to the Pantech Matrix and the Helio Ocean 2, the Exclaim offers messaging and media features in a "conversation piece" design. Call quality is decent and it makes for a good alternative to other Sprint messaging phones, such as the LG Rumor2 and Samsung Rant. You can get it for $79.99 with a two-year contract and a mail-in rebate.
