Apple’s built-in screenshot app is pretty okay, but it’s not quite seamless enough. When I want to file a bug report, or post a humorous screenshot to Flickr, or snap a screenshot to post on Technophobe, I turn to Skitch.

Don’t get me wrong, I still use Skitch for quick and dirty screenshots and annotations. In fact, I use it more than Layers. But Layers gets my vote for coolest screenshot app of all time.
