Features are kind of crummy in a way, because the more features you have, the bigger the manual is. And features are only beneficial if people take the time to use them, wheras speed — if you can print the pages faster, or show it on the screen faster, or recalc it faster — that’s worth an incredible amount. If you can give the users a few simple commands and make the program efficient enough to do what they want with those few commands, then you’re much better off. One sign of very good programs is that even internally they follow that philosophy of simplicity. If they want to do something complex, they call the code with simple operations internally, rather than doing the complex operation from scratch.
