DriveDroid

DriveDroid

This seems handy.  Description from the app page:

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 rescue-system on the go… without the need to burn different CDs or USB pendrives.

DriveDroid also includes a convenient download menu where you can download USB-images of a number of operating systems from your phone.

You can also create USB-images which allows you to have a blank USB-drive where you can store files in. Another possibility is to use tools on your PC to make a bootable USB-drive out of the blank image that DriveDroid created.

Hardware is dead

Hardware is dead

At these levels there is almost no profit margin left in the hardware business. A $45 tablet is cheap enough to be an impulse purchase at the check-out line in Best Buy. A $45 price puts tablets within reach of a whole host of other activities not traditionally associated with computers. Tablets could be used by waiters in restaurants. By mechanics in auto body shops. By every nurse in a hospital. By pretty much any category of work that today needs a computer but where PCs are too expensive to be deployed. These are also devices built entirely for commercial reasons, no government backing, no academic sponsor, no proof-of-concept.
