Like their real-world counterpart, a quickly jotted digital sticky note placed prominently on the desktop can be just the reminder or inspirational message you need. And it won't bulk up the landfill when you trash it.
Software sticky notes are simply movable widgets that contain text, and even the simplest possess some font, color, and formatting customization. Most of the apps I looked at let you add alarms, sounds, and hot key shortcuts. The more advanced programs are surprisingly powerful, adding sophisticated synchronizing features and management platforms to track notes and reduce desktop clutter.
