It depends on your wiring but I've had pretty good success with AV2000 powerline ethernet. I get about 400Mbps and a reliable 2ms ping which is good enough for gaming and streaming from my media center.

The endpoint in my living room also has a wifi AP so signal is pretty good for laptops and whatnot.

In NYC every channel is congested, I can see like 25 access points at any time and half are poorly configured. Any wired medium is better than the air, I could probably propagate a signal through the drywall that's more reliable than wifi here.

So having something I can just plug into the wall is pretty nice compared to running cables even if it's a fraction of gigE standards.
