I'm not sure why everyone is getting ruffled.

I take steamboat's statement to mean that if you have not paid for components/assembly through his website, its not his fault if he runs out of components. This is especially pertinent for early batches. For example, if you are in batch 1, and you have not paid for components/assembly, and steamboat runs out of components because other chips arrive (his own batches and/or other group buys) that have paid for components/assembly, then you will face delays until steamboat orders another few pallets of components.

Assuming the above is true, I also think this is fair. He can't sit on his thumbs hoping that early batchers that are late to pay for components/assembly will do so eventually, while holding back customers that have paid for components/assembly, and their chips have arrived.

So, if you have already paid for components/assembly before the 30th June deadline (or perhaps even a couple of days after that) I don't think you have anything to worry about.
