People who "live in the cloud" with a 16GB iPad have very un-demanding needs. They're people like my mom, who take some photos and send some e-mails. They're not going to buy a $1,300 machine to do those things when a $500 iPad does them just fine.
That's the problem with speaking for the general population, you say "most people need more", someone else says "most people only need X" and the conversation goes no where.
You can make some inferences from the available statistics. The Chromebook is priced like an Ultrabook. Nobody is making any money off Ultrabooks, except Apple. Why would anyone spend as much as an Ultrabook to get a machine that does even less than an Ultrabook? I don't think this is that subjective of an argument.

I think that this depends almost entirely on how slick it looks and how well it is marketed. Plenty of moms have MBPs that they shelled out the extra $1k+ for to take get on FB and send emails.
I'm not saying that it's _smart_ to do that :) but never underestimate the allure of a well-marketed product.
