Simplicity Linux is a Puppy Linux derivative with LXDE as the default desktop environment. It is based on Slacko Puppy, uses LXDE as its desktop and has Chrome as the default browser. It's something we personally use, and have found really useful, so we thought we would bundle it.
Mini is our lightweight edition of Simplicity Linux. It has a few local apps, but most of the hard work is done by cloud based apps. It also features an assistant called Kai Says, which is a little like Siri.
