an easy to use system that provides all the infrastructure for time based updates as well as resource (e.g. memory) management for a multiple-readers (and in the case of services, multiple "writer") situations all while not requiring applets to link against N different libraries for N different data sets (which, sadly, tends to be the norm). it also prevents having to build different bindings for all those N different libraries, gives us one place to manage access to them (allowing for things like remoting), and lets us keep the applet API tiny without feeling tempted to bloat it with things like "cpuTemperature()" (see how many other widget APIs make that mistake..) -- Aaron J.
