I learned a lot from this article. I don't think he is being critical, he is making very well reasoned arguments and is probably excited to get his hands on this device to see if they hold up.
He could wait a bit so it's not assumptions and guesses only.
I know what you mean, but equally if people can’t apply the same principle re: hype and excitement then personally I think it’s nice to have a bit of a counterbalance.
