Okay, this is actually my declaration of love for EverNote, a wonderful note-taking program that totally revolutionize the way I keep notes (and save web pages and organize my activities and...)
Check it out, the latest version is cool:

The standard version is free (gratis). The Plus version is 35 USD, but truly I don't need its capabilities (it adds ink recognition, database synchronization).
When the PDA version is out, even if it's not gratis, I'm sure to buy it.
