The CrossLink from ASUS is a versatile USB accessory. It functions as a flash drive with 2GB storage capacity. It also comes with a cable that allows you to connect two computers directly and provides an incredibly easy-to-use drag-and-drop interface to transfer files at up to 48Mbps.
Another feature the CrossLink provides is shared internet access. A netbook without a wireless signal can connect to a computer that's connected to the internet via LAN and share that connection. It can also access that computer's optical disk drive, and it can be used to sync files and folders between computers.
