What to do when the prospect thinks "all systems are alike"

Have you ever had a prospect tell you (usually shortly after your presentation) that all phone systems are alike? I think this is a prospect telling you that they want the best system they have ever seen (which is yours) for the lowest price (of any of the other systems they have seen). My experience tells me that no two systems are alike. There are hundreds of features and by far there are more things that are differences than there are similarities. If you have done your home work, you have found problems with the way people are communicating now. And you have found unique features (in your system) that can be used to solve those problems. The truth is that systems are really very different from each other. So how do you tell the prospect they are wrong? I have found an effective method of doing this in a non-confrontational way. Something like..."Mr. Prospect...if all you want to do is make and receive phone calls then you are correct...all systems are basically alike...but if you want to improve the way you communicate...all systems are very different. For example...in department A we can do x and in area B we can do Y and for problem C we can do Z". What I have done here is start by agreeing with the prospect...you are correct...they are all alike.... Then, with sound logic I actually completely disagree with the prospect in important areas and back it up with examples. I actually get a chance to reinforce my strong selling points and speak to the reasons why he should buy my product. This only works if you have done the work to identify what your product can do for his business that is above and beyond the basics. Good Selling!
