The problem with Stickies, for me is the lack of easy access. I have to keep them in the doc (or figure another way to launch quickly) OR keep them open all the time. I guess that would be ok IF that wouldn't cause my desktop to be covered with more junk. Stickies makes my computer screen as cluttered as the scraps of paper all over my physical desktop! To find any note, I have to sift through the pile to find notes that may be behind other notes.

The Stickies type apps I've been able to find are still apps that must be launched. They have generally addressed the clutter problem by giving an index or search feature but often have gone into over kill and are no longer simple little apps.

Enter Sidenote, which is such an improvement over the rest, I can't believe Apple hasn't added it to the system. Choose a hotkey or an area of the screen to touch and Sidenote scrolls out for use! Brilliant! You can even sync over multiple machines by setting the preferences to save to a network storage device (I use my Mobile Me iDisk).

My only gripe - No updates since 2007. If I had not been using Sidenote so long, I probably would not take a chance. It generally makes me nervous to use software that has not been updated within a year or so, but I have to say, I'm up to Leopard 10.5.7 and Sidenote it is still operating fine.
