People come to Trek and watch Trek for their own reasons. Some people really get into the hardware and technical specifications and that's cool if you're into that kind of thing and keep it in perspective. Other people are more into the characters, or the social allegories, or the optimistic vision of the future, or the space opera excitement, or the far-out sci-fi concepts and exotic aliens or whatever. A certain degree of consistency regarding the tech is probably not a bad thing, but I suspect that most viewers aren't going to care or notice if the starboard auxiliary deflector array switches location from one series to another.
Says the guy who, honestly, cannot tell a Ford from a Chevy and tends to scratch my head when folks see vast differences between the various different versions of the Enterprise. As long as it's got a saucer and a couple of nacelles, it looks like the Enterprise to me . . . .
