I love Journal, and am thrilled at how much it will help me with my work. I am always in the middle of 4-6 projects that are ongoing and can't be completed in one sitting. These are diverse projects and require different resources. So what typically happens is that I end up with about 50 browser windows open just waiting for me to get back to that particular project. Inevitably this freezes up the computer and . . . well, you know the rest of that story. Spaces give me a way to keep all of these projects and their associated resources organized and readily available without clogging up my RAM. It really is already an invaluable tool for the way I work. And it's so easy and intuitive to learn.
