I'm not a big fan of toucscreens. I used to look after a couple of machines with them and they could be a real PITA at times, even though they were rugged industrial types.
Besides my hands are rarely clean!
As I'm now using Modbus able PLC's from Cubloc I can implement all those original operator panels without too much grief.
Actually Cubloc have a PLC with a built in small Touchscreen with Modbus. This would make a killer pendant for those that way inclined.
I'm actually thinking of creating a screenset either like the Meldas or a TNC control. Both those used the operator panels with the most often used functions as REAL switches. and softkeys around the screen for those menu selections.
Was trying out the Jetcam screen designer last night, that being more flexible seems to be easier to use in creating "real", "proper" or whatever you want to call them screens

I bought a couple of I-Pacs the other day, didn't realise they could only do single keystrokes, so not a lot of use, unless you use a multimedia keyboard to program in some non standard scancodes. Even stuff like CTRL X is not possible it seems.
