Post-it notes are a great way to remember everything you have to do, but being in the Internet era you should take a step forward and start using virtual sticky notes. They're faster, cheaper and of course, more environmental friendly.

Shock Stickers is probably one of the best options available in virtual post-it notes. After installing it, the program sits unobtrusively on the system tray and allows you to access all its main functions via its icon.

Shock Stickers has an impressive array of features: a dozen colors for notes, support for transparency, ability to lock notes, hide them or send them by email, full text formatting, alarm for notes, password protection and even a recycler manager to recover deleted notes.

It's hard to think of any cons about Shock Stickers. I didn't like being asked for confirmation every time I wanted to delete a note, but then I realized I could turn that off in Settings.

Use these great virtual post-it notes to remember everything and save trees!
