I have been interested to see what one can do in Smartsheets. However, I have also ended up debugging the workflows set up by a co-worker--not particularly technical. I guess that I would say that the Smartsheets workflows reduce the need for coding, but not for considering possible states and transitions.

And the creators of Smartsheets seem to have heard and run with somebody's maxim that "It doesn't matter what users say they want, they want Excel."
