Ethereum is still PoW, they released an initial PoS that runs along side the PoW, "verifying" every 100 transactions or so.

The goal is to move entirely to PoS, but things take time.

Why has it taken so long? I thought this would happen in 2017.

Because there are still issues with the idea of PoS. Major one AFAIK is that there's nothing preventing miners mining a fork in addition to the "main" chain, which destroys consensus on which chain is the main chain.
