Obviously you have either a slow internet or a slow computer. Preview takes a pretty long time especially with a lot of images, like my O2 topic. O2 takes me about 30 seconds to load in preview. So I will probably have no need for this because one, its has a gray background so for people like me,who design and use transparent images, it wont work good.
