I used a similar system while doing training before, really neat as people could guarantee more or less that all the development environment was the same across different computers even with BYOD (bring your own device) and people would focus on the training content instead of lose time configuring their PCs. I can see its applications on education.

The most annoying thing in their setup (which may differ from this one) was that some shortcuts would be captured by the browser, so I closed the whole thing multiple times with Ctrl + W while relying on muscle memory.
