DriveDroid allows you to boot your PC from ISO / IMG files stored on your phone. This is ideal for trying Linux distributions or always having a standby system on the road … without the need to burn different CDs or USB keys.
DriveDroid also includes an ideal download menu where you can download USB-images from a number of operating systems from your phone (such as Mint, Ubuntu, Fedora, OpenSUSE and Arch Linux).
You can also create USB-blank images that allows you to have a blank USB-hard. From your PC, you can store files on the USB-drive, but also use tools on your PC to write images to disk.
