I feel that no company is interested with 2d, they all go like cannonball to 3D, so they neglect 2D. One example is the impossibility of reaching the centimeter precision with any of them.
Strictly speaking, IMSI Floorplan isn't a cad program, it is a home decor program and not designed for accuracy. Autocad and traditional apps of that level may not be as easy or quick (or cheap) but the basic 2d tools that they still feature (alongside all the other new stuff) are IMHO still hard to beat in terms of flexibility. I do agree though, it does seem that there isn't any new thinking in terms of middleweight 2d, probably this is because the roll out of BIM software such as Revit automates the workflow from 2d to 3d or 3d to 2d.
Maybe we should make some suggestions to the Archimedes - open source cad project team. They are building a free architectural cad app for commercial use. http://archimedes.incubadora.fapesp.br/portal/project/archimedes-project/
