I have to admit, I’ve been a big fan of the Stickies app that Apple has included with its operating system since way back in System 7.5. It’s fantastic to be able to have a little floating place to type notes and keep track of things right on the Mac, without having to resort to anything as mundane as an actual sticky note.
The one thing Stickies hasn’t had was a good way to access those notes when away from the computer. With OS X Mountain Lion, however, you can make this happen using Notes and iCloud.
