~SD Card size memory chips are still much better than ours, but not insanely better. Battletech video codecs have to be massively better than ours to get holographic video down to the size they do. I'd have to go look at the numbers to compare it to Blueray.
It won't be to long before full sensory VR holographic holodeck light home theaters will become available again (the new Free Worlds League House Book). In the meantime you'll have to settle for holographic TV in your house.
Comstar has some left over data centers on Terra that are staggeringly huge. The planetary defense grid on Terra is running on a 100 yotabyte data center.
The cars on Terra are all fusion powered. Most of the other worlds are lucky if they have fuel cell engines in their hover cars.
We know specifically Arcturus has planet wide multiplayer computer gaming (A Time of War).

[quote name=']Most Taurian worlds also boast a computer network robust enough to support online gaming. Guerrilla-warfare games based on incidents from the Reunification War are perennial hits' date=' as is just about any game with Davions as the enemy.[/quote']
Hand Book House Steiner mentions holographic game consoles.
Battlemech computers are good enough to almost pilot the mech itself. They can handle routing and complex multispectral (visual light, IR, Magnetic, Radar, etc) analysis of the terrain to determine foot placement at hundreds of kilometers an hour (Tech Manual). The Locust 6M can hit 302km/h while firing sideways. The pilot is not picking where the feet go or making sure it doesn't run into a ditch or too big of a tree. The DI computer handles all of that.
