Microsoft really wants you to do some video conferencing, okay? Why else would they release the LifeCam VX-5000 and VX-500 webcams? Apparently gunning for some of that juicy video-chat market, the boys and girls in Redmond have introduced two models sure to find a home perched atop any monitor. Both cams sport VGA resolution and play nice with Windows Live Messenger -- we assume they're USB 2.0 devices, but Microsoft doesn't seem to want to tell us. The company is also releasing a headset, the LifeChat LX-2000. The VX-5000 will be available in June for $49.95, while the VX-500 and LX-2000 hit shelves this month for $16.95 and $29.95, respectively.
