Allan, I think Mike is great. I've been a customer of his since the TAS days. Sadly, he wrings them out AFTER they are designed.
And Allan, THIS HAS GOTTA BE A KIDS TOY. It is the traditional interface to running trains. Handhelds are great, but they're only part of the story.
That being said, I think it's important to let little kids run the trains. And the more intrusive supervision they have, the less fun they frequently have. Johnny, don't do this, you're doing that wrong, Sara stop pushing the button, etc. If you want them to love the hobby and get involved in the hobby, you can't always being on top of them and "correcting" them. You have to cut some slack -- which DOES NOT mean no supervision. You just have to decide what's important.
In fact some of the absolutely DUMBEST things I've seen have been done by adults. On my layout!!
BTW, an interesting topic might be how old were most of the Forum members when they started with trains. And was there constant supervision? I suspect not and I know there certainly wasn't in my case.
So I'm back to the question -- it might be neat, it might have great gauges, but will it stand up to the kids? I think that's a very fair question.
