Do you keep a list of books you've completed, or books you want to read? There's a recent release from Iliumsoft
that might help you do that on your PDA or smart phone.
is "the top list and information manager for Pocket PCs, Palms, Smartphones, and Windows desktop or notebook PCs." Not only can you use built-in templates, but you have access to all kinds of features like outlining, alarms, pictures and list sharing. In fact, you can export to either HTML or RSS/XML. This is clearly an upscale list manager with many flexible and advanced features and a nice look to it. You'll have to get used to making the most of your screen real estate with sophisticated lists, but it's amazing what Iliumsoft has been able to produce.
My favorite "feature" is the support for multiple platforms - Pocket PCs, Palm OS, Windows Mobile Smartphones, Windows PCs. It's a big advantage to be able to move between those platforms seamlessly, or to export my data if I go to an unsupported platform two years from now.
And just in case you're wondering, yes, you can even do the most traditional job of list software - shopping lists!
