I don't know about you, but I'd personally rather pay the $5 if I don't need a serious cluster yet. How much in actual absolute dollars do you think this is going to cost you, just in order to figure out exactly how it works, and what other AWS widgets you'll also need to pay for in order to use it effectively?
I am a human, basically looking for a stepping stone on some actual cloud to land on that is comparable to Minikube, and this sure isn't it.
