My DCS remote now collects dust. I had two and sold one. Once you get the Wi-Fi working my view is you will rarely if ever want or need the remote.
I'll offer you $10 for that DCS remote that's collecting dust, no reason to let it go to waste.
In case you missed it, I agree with RJR, a major problem with the WiFi is no tactile feedback.
At some of our modular shows, I find myself running two and sometimes three trains, typically a couple of novelty items and a standard consist. The WiFi would result in far too many crashes for me. I have a number of Legacy and DCS remotes, and I'll keep using them, thanks.
