| The Amazon Kindle 3G Reading Device ($189) provides very convenient access to the GPS bus-hea tracking system. There is no monthly fee. Now I enjoy reading Kindle books (many free) while waiting for and riding the bus. Most important, I know when my bus will be arriving. The free internet access works anywhere on the island. Once I locate a stop and enter it as a bookmark, a couple of clicks brings up a page clearly listing predicted times of bus arrivals at the stop for the next several hours, quite accurate as arrival times are nearer.
