Linux AIO (All In One) project may prove a big blessing for Linux Software testers, developers and web bloggers. It can also be very useful for normal desktop users.
As you already know, all Linux distributions support multiple desktop environments, everyone has some favorites, but most of times, you have to try more than one desktop environment on any distribution to decide which one best suits you.
Isn't this time consuming to download multiple desktop environments for same distro and keep installing them? Its not only time consuming, but you spend you network bandwidth, your system resources to carry out this task.
This is where Linux AIO Project comes handy; it combines all of the desktop environments available for every popular distribution and wraps them up in a disk image for Live system. You can then burn this image to DVD or a USB drive and boot your system using this, or can use Oracle Virtual Box to create a virtual machine and boot this virtual machine using respective AIO ISO image.
