It's a solar cell! It's a VoIP phone! It's a USB stick? Convergence isn't just limited to cellphones and laptops, pallies, we're already seeing companies try to cram in functions and features to the new ubiquity: USB drives. Enter A-DATA's as yet unannounced Solar and VoIP Disks. The Solar does as you'd expect, collects power and displays how much storage you've got left (although we're not super hot on the idea of an unstable current pulsing through our flash drive); the VoIP, unlike the Vonage V-Phone, actually provides audio functionality for calling as well.
