Glas is the larger version of the MobiGlas and is also manufactured by MicroTech. It has more surface area to work with and a more robust computing power but otherwise offers similar features as the MobiGlas.
Glas is together with other computer systems the baseline of schooling nowadays. A variety of companies, through imperial subsidies, have created learning programs capable of educating children to achieve Equivalency (high school education). These programs tend to be used on frontier planets and other rural environments that lack ready access to an actual school.
