Mplat's FlashPhone F2K isn't the first VoIP phone on a USB flash drive, but it is the shiniest and, oddly, the wettest. Like the other devices, the FlashPhone F2K will let you make VoIP calls from any computer simply by plugging it into the USB slot and using the unit's built-in mic. The device comes standard with Skype voicemail software but it's also compatible with MSN, Google Talk, and other VoIP services. Prices start at about $40 for the 128MB unit and go up to $80 for the 512MB model.
