VMs have so much utility, so +1 to the author on the nerd nugget for compartimentalizing the use as a game cartridge.

VMs and VEs (environments) have gotten so portable that IOT and 5G will have to compete with raw storage (TB's) for the best user experience in a post-filtered world.

Possibly OT (or use case), but I've demod LTSP [0] to run multiple environments on a single server (PXE menu) and clustered multiple LTSP servers (bouncing to other LTSP menus by manually adding a server list to boot menu(s)) and treated them as books with chapters (each LTSP being a book).

Customizing each chapter by OS needs and media/content/apps has so many uses (immersive news,learning,entertainment) and paves the way for offnet productivity/entertainment that currently doesn't exist in the market (ala Home Library/Encyclopedia Server).

LTSP was not as PnP as it needs to be for consumer use (and external PCIe form factors were pricey), but anyone writing a VM (or decorating the interior) is already riding the next wave of physical data subscriptions/refills that bypass metered networks (SDCs or SSDs in TB capacities with OS agnostic data) for 8k video, VR and compilation/mixedtape datasets.

Portable VMs are a trend waiting to happen, so anything you can learn about it (inside-out) is not a waste.
