I think this thread has descended into a grouchfest.
I have reached an age where I'm happy that my 2001 DCS system (all software upgraded, thank you) can control every MTH DCS loco I have ever bought (over 2 dozen), plus my ancient Lionels (add another 6, including pre-WWII). I like the old style remotes which, while older technology, make the trains (many at a time) go where I want them to go, without my have to flash through screens.
No, I am not a Luddite. I was one of the first users of a 2 WIU system, providing test data. But it has been several years since I ran trains using them. They sit on the layout blinking at me plaintively, while I run my trains.
