That was fine until our six children began getting iPhones and wanting to connect with us in ways other than voice phone calls. So, I reluctantly got an iPhone, and was surprised that I did not hate it. I am not on it all the time, but I have found it to be quite useful in many ways. I will probably buy the interfaces for both systems and use the phone to iPad (yes, I gave in and got one of those too) to control the trains.
I also finally got iphones for my wife and myself about 3 months ago, retired my old flip phone. Reasons were very similar to yours (and my wife wanted one). I don't think I've made but one or two actual phone calls, but I have used it for a ton of other stuff that I didn't know I was needing (or missing) until I got the iphones. I have been quite surprised by the number of uses I have found so far.
I do have the DCS wifi and have used it some. However, I still prefer the DCS and Legacy remotes on a regular basis. I am coming around somewhat and realize that I'll probably have to switch one of these days. Not sure I will add the Lionel wifi, but you never know?
I do think MTH might be a little premature on discontinuing the remotes? It still seems like there are quite a few that prefer the remotes, but I have no idea about their internal workings and maybe there is much more to it than we know, such as costs, obsolete parts, problems adding future features, design changes etc. I also suppose it is impossible to keep everyone happy all at the same time. That quite a tall order for anyone!!
