A majority of today's computer peripherals utilize USB technology. Keyboards, mice, printers, cameras, scanners, thumb drives, drink warmers, and even foam missile cannons all connect through USB. For real convenience, it would be nice to be able to share all of these USB devices between two computers. You wouldn't even have to reload your cannons, just hit a button and switch to the next one! This is where the Ultra Products 7 Port USB Buddy Hub comes in.
