There is a trial version of TaskPad Pro now available at Handango.
I use MemoPad Pro by the same developer, and like it. I find both programs simple-to-use, inexpensive ways to organize information that doesn't fit in other applications. I really like their web-based application that synchronizes with their Blackberry applications.
BTW, the user-review on Handango regarding TaskPad Pro that states that the notes aren't visible or editable on the handheld is either out-of-date or just-plain wrong. You can view and edit the notes field on the Blackberry.
