That is the question.
I've been away from the hobby for a few years and apparently missed the Bluetooth revolution. A squirrel got into the basement and ... well, it's painful so I'm just not going to talk about it in detail. Suffice it to say, I shot it with a BB gun (which got someone on this forum all bent out of shape) but not before it did substantial damage to my layout and many trains, completely killing my desire to even go down to my basement. However, recently my five young grandchildren's eyes nearly popped out of their heads when they saw my layout so now, with their enthusiastic encouragement, I'm getting back into it.
So, back to my question: What's the big deal about operating Bluetooth capable LC+ engines with an app on my smartphone? Isn't the LC+ remote just as easy or easier to use than touching little icons on a phone or tablet? And isn't the remote easier for a child to use than a phone app? Does Bluetooth have any advantages I'm just not seeing? Frankly, for the extra $ a BT engine costs, I don't see any benefit. I must be missing something, but I just don't know what it is.
