Your off again suggesting that serious modellers can't consider anything other than what you prefer. Take a look at some exhibitions at some serious modellers and you will see them happily using touch screens and button devices.
Bluetooth may offer a form of control in the future and when it does it will be used by modellers whether they be serious modellers, hobby modellers or simply dabblers but please stop suggesting that this is anything more than a potential alternative to the existing control options which are mature and provide the majority of modellers with what the want.
Sorry I'm really not sure where your comments is derived from. My post described my thoughts on how potential developers might look at expanding the use of their applications to devices that are not necessarily touch screens. I was not prescribing that the only way forward for future development is the use of tactile control. My observation was based upon conversations that I have had with a variety of modellers who although interested in what the new Bluetooth and WiFi control platforms offer. Would feel more at home if those platforms themselves offered the ability to use more tactile control surfaces.
Personally I have no particular issue in whatever means of control a modeller chooses to use, other than that it doesn't put others in harms way or cause the formula for Pi to be re-adjusted.
Your own comments questioned what was the benefit of such control platforms for the serious modeller and by that I assume you mean above and beyond what is available through the use of DCC. Unfortunately it's not always easy to keep a discussion point brief and within the attention span that most of us would assign to reading a posting, but here goes and this list is based on what is currently sat on my modelling shelf in the form of BlueRail Blue, Horse control board
1. Fully Bi-directional exchange of control and feedback data between Locomotive and operating device.
2. Fully wireless hands free control at approximately 25% of the cost of buying a Lenz DCC system and the required add on's (and thats working on the assumption that I purchase a brand new tablet smart device to operate the Blue Horse board).
3 Significantly easier access to adjusting the performance characteristics of each Loco. No need to access CV's and refer to tables of values. Adjustments are presented in an easily understandable graphical manner (switches off/on, or adjustment of values with a slider). Double heading and speed matching loco's under BlueRails App is a doddle. Certainly less of a ball ache than achieving the same level of control by adjusting CV's on my Lenz system.
4. Set Up Time. No messing around with Loco addresses or programming tracks. Each bluetooth board has a unique number in the same way that each computer has a unique Mac address. Smart device finds a board within a few seconds and it takes a few seconds more to assign a full alpha numeric name to that board (The Monocracy App lets the smart device take a photo of the loco and and presents it on the screen when that loco is under control).
5. Extra layout operator. No need to purchase additional manufacturer specific throttles, interfaces or accommodate extra wiring, Oh! and the inevitable head scratching that comes with it). If your friend doesn't have access to a smart phone or tablet device then a £50 tablet from Tesco's will do (don't hold me to that price) and download the free board manufacturers app (not sure what the current price of Lenz hand throttle is but I'm guessing it's not a whole bunch cheaper and you can't use it for much all else other than play trains).
6. This really should be a point 4a. No clash of Loco addresses. As stated every Bluetooth board has a unique address. So if you invite your friend along to your layout with his Bluetooth equipped loco's, there is no need to amicably start sorting out clashes of DCC loco addresses because with Bluetooth it isn't going to happen. All you need is to spend a couple of minutes making sure that your smart controller of choice and their smart controller of choice can see exactly which loco's you need and want to control.
7. And this to my mind is the real winner. If you can navigate your way around an iPhone then achieving fully wireless control, adjustment of loco performance and features, double heading and such like are within your reach. No need to reach for less than friendly user manuals or post questions to forums and be made to feel like an idiot because you didn't know there was some amendment to the cv table for that decoder you bought that was one of a bunch that the manufacturer no longer makes. No need to wish that you had payed more attention in science class to how to understand circuit diagrams or wait patiently at some exhibition and hope that some friendly layout operator might explain to you how to wire in a USB interface to your DCC controller then how to set up your laptop via that interface and what program to use to achieve train control that also provides access to the ad hoc wifi network you need to create so that you can use your iPhone has a hand throttle........ I think you get my drift.
All this is available now as the product stands today. Being blunt. the bulk of what fifteen years of DCC development and hundreds of pounds worth of required customer investment can now deliver in model locomotive control. Bluetooth can do for forty quid and the loan of your errant teenagers smartphone......
And if thats not of interest to any modeller, serious or otherwise. I really don't know what is.
Apologies for the typo's and bad grammar. I don't have the energy to keep re-hashing the same arguments.
