I failed to understand the awesomeness of Ethereum to be honest. I also think, most people who tried to explain it didn't do good job either. The most frequent explanation you would hear is that Ethereum is a Turing complete world computer that can do anything. But in my opinion, the above sentence is misleading marketing. You would also hear statement like "Ethereum is a blockchain that runs code". Well a blockchain is a datastructure, like a linked list. A datastructure only stores data, a datastructure doesn't run code. If you look closer (correct me if I'm wrong), each program has to be executed by every single machine in the network to get cross verified. So the computation power of Ethereum is not the combination of all computers in the network, like you would imagine of a "world computer". Also, the program has to be deterministic. This means it can't have random number, can't read data from outside APIs. I don't think being Turing complete is that useful.
