The IS is a very big improvement over the old Calculate function as far as ease of use and interactivity. The Calculate function, if somewhat mastered, is a very powerful tool and can do much more than the IS. I use Calculate to do a lot of quick down and dirty take-offs and quantities, and I also use the IS for schedules and other documentation. For most architects/builders the IS is all you really need to produce the data required.
