Hi All, As a system integrator, I used to build control systems for customers using industrial/embedded PCs, but as Windows has replaced DOS in the commercial sector, unless I packaged my product as a proprietary system, many of my customers will query if they are advanced enough since they are still running on DOS. However, to me, I still find DOS the most economical and programmer friendly o.s. to use in many industrial applications, especially when a graphical user interface is not needed. Am I making a wrong decision of retaining a phasing out o.s. in my product? Or can anyone suggest me some ways to make my customers confident in my DOS based systems?
