  You can actually download tools and run the contracts, and during the public stress test people posted contracts to the test network. Not every contract needs external data. A simple crowdfunding app, for example, doesn't need one. Hit the funding target by the deadline, forward to the fundraiser, otherwise return to donors. You can try out several sample contracts by going through the tutorials at ethereum.org. The only reason oracles are complicated at all is that people don't want to trust them. If you're willing to trust a particular account for some purpose, it's trivial. Trusting a majority vote among several named accounts is also simple. It's the fully decentralized and low-trust solutions that may take some effort, but that's not an issue with Ethereum's core technology.
