Lessons in number portability from Hong Kong. Basically, higher churn (or lower switching costs), more price competition, and more price-sensitive consumer buying into mobile service.
The Slashdot post on this article says essentially 'yeah, it's great that number portability heightens price competition'. These are the same guys that hate Wal-Mart and the tech industry for killing jobs in the name of cutting costs. Note to Slashdotters: price competition, Wal-Mart, cost-cutting, and a lack of innovation are generally directly related.
