For the next 11 hours or so, ListPro by Ilium Software is 51% off. Most of you know what ListPro is, but may not have taken the leap yet to buy it. For those of you that don't, think of it as sitting somewhere between your Outlook Tasks and a rich flat-file database. A ListPro list can be nothing more than a simple checklist of items or can be as elaborate as having dates, columns that automatically perform calculations based on data in other columns and even trigger alarms if desired.

If you've tried it but never taken the plunge, now is the time at only $9.95. If you have never tried it, you can download a trial version at Ilium Software's site, but don't spend too much time playing with it. At midnight EST (I think), it reverts back to its normal price

ListPro runs on Windows XP, Vista, Windows Mobile Pro/Classic (Pocket PC), and Windows Mobile Standard (Smartphone) and will sync list files via ActiveSync or Windows Mobile Device Center between your PC and mobile device, assuming you have purchased the correct clients.
