The comment I hear most often from current and prospective clients is the software is much easier to use than the DOS and UNIX programs. If you are entering an invoice and need to enter a new vendor, you just do it. There is no need to exit Invoice Entry, and start Vendor Maintenance. If you don t know a code, you touch a button and a search command is at your fingertips. That is true because they are graphical and more intelligent programs.
Computer power is a non-issue today because the cost of hardware has dropped so dramatically.
Another argument is that data entry is not as fast in Windows as in UNIX and DOS . This is true, if you measure productivity by counting keystrokes. However, it is much easier to change functions in Windows, nullifying much of the keystroke advantage. Other productivity tools, more plentiful with Windows applications, are eliminating much of the keyboarding argument. In utility billing, meter reading entry is eliminated by downloading readings from hand held devices.
