Earlier quoted context omitted.
I think Apple should take every competitor seriously and I am sure they do. My point is that Google has a history of being unable to ship anything properly. And until we see them do so and with a sizable profit margin then they shouldn't be considered in the same league as Apple. And the important skill is not making the laptop it's in the supply chain management.
You just said "nobody will or should take them seriously" and now you're saying Apple should take them seriously. Google shipped tons of products properly, if you're talking about nexus devices, they don't even advertise those much, they're more of a testbed for what's coming.
And we are talking about hardware here. They have consistent failures in shipping hardware.
