I've traveled pretty extensively across the world for work and very few places have an internet connection that compares to even a modest broadband connection in the US. Not only that, I deal with this problem weekly from our partners in 75 countries across the world who don't have good internet connections. As well, you're discounting the world's oceans. I've worked on a ship where we provided an extremely limited internet connection that would not be suitable for rapid development work.

I'd say it's a pretty small portion of the planet that has a decent internet connection, but the detail is how you define "decent".

Sorry, there is no DECENT internet connection in China

And yet, I still am able to work here. Barely, but still (helps that we have our own line from the office).

"Large portion of the planet"... you've got North America, South America(some exceptions), Europe, a good chunk of Asia and Australasia. That's a pretty reasonable selection of places to live isn't it?
