Vonage America introduced its V-Phone - actually a 256 Mbyte USB flash drive with all the software necessary to enable VoIP calls on virtually any PC, laptop, or any other electronic device with a USB port and a broadband connection. The V-Phone comes with a standard 2.5 mm stereo earpiece microphone that's also compatible with many cell phone headsets. Software on the V-Phone updates itself on the device's 256 MB flash drive. Phone history and contacts travel with the flash drive, not the host PC. The device is plug-and-play, Vonage said. When customers are surfing the Internet at a Wi-Fi hotspot, they can plug in their V-Phone and make calls, too. Vonage's flat-rate, full-featured calling plans apply. The Vonage V-Phone is not currently compatible with Apple, Macintosh, or Linux Systems.
