To be quite honest... I suspect anyone (well okay mostly anyone) who even REALLY needs 7 screens hasn't put a lot of thought into efficiency, and making folders to contain a lot of their shortcuts and other items. I had 7 for a while but was really only using 5, and even then they were just filled with pictures from the photo frame widget lol. Like I said before, I feel confident that 4 will be enough with DxTop given the app dock and the second tab for recently used stuff.
