Not in Cologne (~1 million) nor Dortmund/Bochum (part of the 'Ruhrgebiet' metropolitan area, which Wikipedia estimates includes about 12 million people).
Guess not a first-world country?
We're probably on the same side: I would NEVER go for a Chromebook. Always online is stupid. Mobile sucks on trains here, so forget about data on the move. Hotspots don't exist. There are still lots of places that I visit that have little to no usable data connectivity.
I have no clue what the Chromebook is for, but it would be a giant failure in my circles and my environment.
Not that the over-arching sentiment of "you shouldn't take the existence of an always-available network connection for granted" is a bad one. It's just that saying, basically, "These devices aren't suitable everywhere; consider market segments that may be less mature than the big, contemporary Western one you're most familiar with, for example" is a little bit of a weird and not terribly convincing way to express it.
The whole point of a netbook (which is really what a Chromebook is, with the tainted name dropped) is something that has most of its functionality on the web rather than a local device.
Had one of those machines for work. Even after a fresh install, the lag was positively infuriating.
