Hi Justin,

Of course not, but it still a good complementary while you need to carry on you job after office hour. It provides a full set of spatial function that will cost you a lot in ESRI package. In Hong Kong ArcGIS is divided into certain kind of product level that if you need more function (extension), you need to pay more. For example a standard ArcInfo will cost you 120K HKD. Here a GIS analyst is earning 25K/M.
