For me personally, a Googlebook would not be my primary computing device, it would be a companion device.
There are a ton of reasons why I could never use one of these all the time. They are too dainty, the screen size is too small, the glossy screen, lack of ports, cramped keyboard, no num pad, probably impossible or near impossible to replace or upgrade internal components, what I'm guessing will be a lack of desktop-class applications I use. I maintain MS365 Business and Adobe CC subscriptions, those experiences would be hampered on a Googlebook at least right off the bat.
Other than to play around with, I have no interest in Linux. I would need Windows in some fashion or some virtualization voodoo to continue Midland and Uniden programming software, Escort and Uniden update software, There is still no audio media player application better than Winamp 5.x IMO and I have yet to find a RDP management app that fits my needs better than mRemoteNG.
