Simply said, TodayAgenda is one of the few must have programs out there, there are a few others like Live Search, Mobile Shell 2 and GPSToday for example, but TodayAgenda stands out amongst the crowd.
Firstly, TodayAgenda is completely free and is more than well supported, and is one of the best tasks, agenda, and calendar plug-ins for Windows Mobile Pro there is and completely obliterates the stock calendar plug-in.
The reason TodayAgenda is so cool is it allows the user to completely customise their calendar white the tasks appear on the today screen, and lets you control fonts, size, colours, height as well.
