long known, Sanyo isn't the only company contributing goodies to the opening volley of CDMA Direct Connect devices for Sprint -- LG, Motorola, and Samsung all want in on the action, too. LG brings the LX400, featuring a 1.3 megapixel camera in a burgundy shell; it's not our cup of tea, but folks looking for something on the non-rugged side of the PTT spectrum might find their soulmate here. Next up, the Motorola V950 is pretty notable since it marks Moto's inevitable foray away from its own iDEN tech and toward something just a little more modern to support the push-to-talk functionality its users so deeply love. It's a media powerhouse, too, thanks to external music controls, a microSD slot, stereo Bluetooth, and a 2 megapixel cam. Finally, Samsung comes to the table with two models: the rubberized Z400 (surprisingly appearing to be the most hardcore of the foursome) that trades consumer-friendly features for a tough shell -- though they've still felt the need to slap a 1.3 megapixel cam on there -- and the Z700, a fancy, refined set that looks fit for duty in the most fancy of pockets and shares much of its spec sheet with the Moto V950. Pricing and availability haven't been announced for any of the four, but we imagine they'll be pretty reasonable given the overall modesty across the line.
