Touch panels, iPad, Air Manager, Spacedesk sanity check

Thanks for the detailed response - I think I will be hitting the discord as my questions seem to have questions, which have lots of little baby questions running around loose. Your setup there is very impressive, somewhat in the “my wife would kill me” zone but nonetheless impressive. I expect some of this I’ll figure out as I try it.
I see you have a few what I assume are touch screens in addition to the iPads. Plusses and minuses of one over the other? Size is the first & most obvious difference, curious if there’s any others.
