The isostick is a USB flash memory stick that likes to pretend it is also an optical (CD/DVD) drive. As far as the computer knows, there’s two things in that little device: some flash storage, and an optical drive.
The idea is to put CD/DVD images, also known as ISO9660 files or “iso” files for short, on the flash memory drive and then you’re able to “insert” any one of those files into the optical drive. The computer will think there is a real optical drive sitting there with a disc in it!
This could well be an invaluable tool for IT admins and geeks alike. Also, the product’s Kickstarter page indicates that the project is on the verge of receiving funding.
