On price, you could definitely do better than $8/million steps, $0.25/GB written and $0.15/GB-month for state storage, but if you were designing something generic on S3/DynamoDB (state + status) to support all use cases at all scales, you'd probably end up spending something around the same order or magnitude.

But if you did that, you'd also have to implement it all yourself. This is a relatively simple checkpointing workflow orchestrator across standard Lambda functions, but with some really nice touch surfaces in the Lambda API itself.

What's only a footnote in the announcement is that this is only us-east-2 (Ohio) and TypeScript/JS + Python at the moment. Basically a public preview release. I look forward to seeing where they take this.
