I have been playing with the MTH WIU on the short line Christmas Tree RR. No doubt this is key to attracting those younger than I. I'm using my cell phone.
One question that came up was with regards to ergonomics and size of the WIU interface. My Galaxy cell is certainly up to the task, but so is a larger tablet. I like the idea of only one hand needed to hold the device.
Then I looked online and found several 7" Kindle size devices that seems it might be a good size for a dedicated device to use the WIU and control the trains in your train room?
Yes, I realize I may be over thinking this whole thing - but maybe not.
