I’ll agree with the slowness issues, but I’ve found OpenSCAD extremely useful for functional hardware, especially when implementing something against a spec or physical measurements that need to be iterated open. As examples, I’ve designed a PC chassis and working housekey copies in OpenSCAD, both of which benefit massively from being fully parametric.
On the measure tool, it usually isn’t necessary because your critical dimensions should be inputs into your SCAD rather than outputs from it. Even so, there is a pretty useful set of modules for generating dimensioned drawings: http://www.cannymachines.com/entries/9/openscad_dimensioned_...
