Interviews with Logitech about the Space Navigator and NASA about World Wind from ISDE5 in June 2007.
The Economist has an interesting article rating the most and least livable cities in the world. Canada and Australia come out ahead on the most and Africa and the Middle East fall hard in the least. Interestingly (or maybe as one might expect), the US is not on either list. They’re not 100% clear on what they define as “livable”, but it does mention a number of broad metrics considered. There is also a more full report linked at the bottom, but access to that costs money.
