That's both rude and unhelpful, and does nothing to address the original point (that they should focus on availability), which I would tend to agree with.

I'd say more blunt and to the point. Also, it doesn't help now, but in future it certainly will.

Don't make plans around pre-release or limited hardware.

Blunt and to the point: "Depending on a product with a flaky delivery issue is a terrible idea".

Rude and unnecessarily offensive: "You are an idiot".

The second one fails the "say it to your face" test in the site's guidelines:

"Be civil. Don't say things you wouldn't say in a face to face conversation."

So, better to do nothing than to try something imperfect?

Sorry, I shouldn't be awake at this hour (See AWS thread). However the number of upvotes I immediately got seems to indicate my subtly suggested solution was quite clear to others.

Or it might signal that which is all but known on HN, that many of its users are mean and spiteful, especially in the early morning.

Unfortunately you cannot measure the number of people who would have downvoted but did not have the ability.

Yeah, guess he shouldn't have had that brilliant idea when they were so hard to come by???
