Any command with more than 1 page of documentation will only be used as a last resort. Speed is proportional to the time you have to wait. It doesn't matter if the new software does 10,000 commands in 30 seconds versus 1 command in 2 seconds with the old software. The 30 second wait is longer than the 2 second wait , thus the new software is slow. Salesman are often taken at their word, while everyone else has to prove it.
Good training leads to remarkable payback on computer use.
Software training budgets are the last thing funded, and the first to be cut. The longer you evaluate software, the more outdated it will be by the time you use it. Customer driven software is great for the short term only. Innovation beyond customer needs and wants is the only way to stay ahead in the market. Customers that know the least about the software make the most demands.
