I'm planning on buying a DCS system after the holidays. I was debating between getting the Wi-Fi system or the remote. I'll be getting the Wi-Fi system now. I have a tablet I can use for the app and it shouldn't be hard at all to figure out how to use it, especially since I haven't used the remote before.
I have to figure that at some point the controls will just be built into the locomotives (ala Lionchief) and controlled via Bluetooth.
