"Not sure of what Eliot means by tethered."

Gee whiz, I thought I could not be more clear.
The way the Lionel Ipad app is currently being designed, you cannot use the Ipad and your Cab2 at the same time unless you have three or four hands. If you are holding and using the Ipad to throw switches you cannot possibly use the Cab2 to operate any loco functions because it is practically physically impossible. The idea is to maintain remote functionality.
One cannot hold both and use both at the same time to do these things.
If you mount your Ipad somewhere, you will have to get to it to throw switches or turn blocks on and off. On a layout my size with power in an aisle, it is a physical impossibility for me to mount an Ipad in an aisle and get to it to throw switches in time or if anyone else is in the aisle.
In other words, Lionel needs you to buy multiple Ipads to mount around the layout or hold the Ipad while someone else runs your loco. You cannot possibly do both at the same time while holding the Ipad.
Ergo, you will really be "tethered" to the same paradigm of standing by the Ipad wherever it is. Just as you would have stood by your control panel.
Soooooooooooooooooo,
If Lionel puts the Cab2 on the Ipad app as an icon with the same functionality it has now, one could simply carry the Ipad around and do whatever you need at the moment.
It seems to me that Lionel is making an economic decision in favor of selling more Cab2's or Cab2L's and hope that we use the Ipad app. To me, there is little difference between what Lionel is offering to me by way of this app and what thousands of other Ipad apps do for me. That is . . . . Nothing. Really, it is worse. I would be giving up my remote control in order to use it. I, therefore, proclaim that for remote control users of large, complex layouts, the app as I understand it throws me backwards.
