I've been using Notelens for over a year, now. It is very basic. It only works with textual information -- basically, notes (no rich text, no graphics, no HTML -- just text). It does, however, synchronize these notes with Outlook. This is the primary reason I chose to buy it. I can use Notelens as my primary note-taking app on my PC (it's fast and always open), sync the notes with Outlook, and then when I sync my Palm with Outlook, the notes sync over to my Palm.
Last month, Notelens 1.07 was released. With that version, Notelens became a free program. Worth a try.
