Most people I know use their laptops to browse the web, and do some word processing. Many of them don't know the differences between a computer and the internet. If for some reason they cannot get to a site or their internet goes down I hear “my computer is not working.”
I think Google has a chance with users describe above. Readers here at TH might be reluctant to by an internet device.
Even though I understand where Google is going with this, I do a lot more with my PC (e.g. video & photo editing, publishing, gaming, etc) than just browse the web.
