Right, it was a game console, and not even a particularly good one.
A real computing device (I'd accept tablets, but really, enterprise desktops and especially servers) would be entirely different.
What I really care about is servers which can be trusted to be "fair" by all parties -- server operators, software operators, and end users. There is absolutely nothing like that today, and it's impossible without trusted computing. It's unclear if trusted computing itself is feasible (it's theoretically possible).
If it works, we end up with Vernor Vinge's _True Names_
Now, it's a console with some good games, but I wouldn't rate it as equivalent in social impact to electricity or nuclear weapons.
