The Tempo Wireless Trash Can from CagninaDesign is actually an external hard drive, which does double duty as a bin for your deleted files and also as an external storage device. It is designed to resemble the ubiquitous ‘Recycle Bin’ on your desktop and has Bluetooth connectivity to interface with your computer. As the 250 Gb space fills up, the external Leds light up from the bottom to show the space available.
Unfortunately, it is still a design concept. If their client Intech ever gets around to producing this thingie, count me as one of their customers.
