Right now you can buy gold on eEhereum (Digix) and it works. You can also gamble in a provably fair way (Rouleth, Etherdice, etc).

When you get a new commodity like Ethereum, you actually expect a period where general tooling is being built - this is due to the ecosystem having to go through the stages of innovation all over again for a new commodity:

Looking at the trajectories of what's being built in the ecosystem right now, I'd say we're just exiting the custom built stage, and we'll start seeing products (which is what you're really looking for) in the next few months.
