Are we close to a pure DC (or hybrid) household?
Edisons dream might come true

No because Edison wanted to distribute power (over long distance) using DC which is cumbersome and lossy. That's why we use AC. The appliances you talk about take only limited amounts of power. Using a DC distribution system for that is also lossy even over the short distances inside your house. To limit the power loss thick (copper) cables would be needed making it an expensive solution.

Your "problems with AC" are not really problems if you see how cheaply we can now make power adapters. And although maybe not optimized I bet it is still more efficient that having a "low voltage DC distribution bus" running around your house. This is due to the cost of copper as I mentioned above. And you need thick copper to limit voltage drop = power loss.
