Computex 2006 So you'd thought there wouldn't be any new ideas for USB memory keys...think again.

Adata showed off a solar powered model at Computex, though the solar cells only power the small LCD display - but as this only draws tiny amounts of power to show you how much capacity you've got left, there's no need for a battery.

Besides the solar powered display, there isn't much to this product - it's available in sizes from 128MB to 1GB and should be available shortly.

Adata was also showing a similar device using an electronic paper display. This model also shows a small pie chart graph and digital representation of how much space is left.

Finally, Adata had a model with a built-in USB sound card that ships with a retractable headset. This allows you to have a VoIP solution alongside your USB memory key, as long as you're happy to carry a small headset around with you as well. ®
