Well, things just got simpler - because of what I can't do with the Luna Display.
Letting the computer and ipad go to sleep meant I had to wake the computer with the TB, but I still couldn't actually do anything because the connection was lost - and I had to sign in to the computer first and maybe I could have done that blind while the TB was paired to it. But even when I went to the computer to sign in, the app still didn't have the connection and it told me to unplug and replug my device. That wasn't necessary - I just quit the app and launched it again. But that one necessity does mean the only way I can use it is if I'm already running the apps, have set the display properly, then still use the computer, via Luna Display when I go to bed - or at least use it before it goes to sleep so that gives me a small window for starting.
I suspect that will be a rare use case for me. After all, if I'm not done working with the computer, why go to bed? But there are times I wake up and I want to try something I thought of rather than wait till morning. This might be something involving TB testing, though until we get new firmware, that isn't likely just now.
Of course, it could be treated like going to bed and reading a book to get sleepy. That may or may not be a use case for me. I'll just have to wait and see about that.
Another use case may be to use it right in front of my monitor. With a proper setup, I can have the TB on my lap, ipad propped up immediately in front of it so easy to reach out for something to tap instead of reaching for the mouse. I suspect, for me anyway, the mouse will be worth the reach since everything is bigger on the monitor, but we'll see.
If I was an artist, it may work well in front of the mac as a sketch pad. I know the company also makes a software solution for that which doesn't require a Luna Display but will also work with it.
So I'd say, for me, it will be more of a novelty item with limited use. It will let me move to another location in my apartment and still see the screen for things not native to the iPad.
It would still be good to automate the display settings. I found an app called SwitchResX which does cost about $16, I think, which looks like it will do the job - and it lets you have it change the resolution, etc, based on the app you are running on the Mac. I'm assuming that means whatever app you have made the focus (rather than only being able to have one app Window at a time!). If so, then I think the process would be like this:
Launch luna display on the ipad (I think this would have to be first so the display settings offer the "mirror" option and then the Luna Display option.
Laund luna display on the Mac - then SwitchResX would (I hope), automatically change the settings.
I still see possible issues with that. After all, unless I made it the choice for all apps, it would change back, I guess, as soon as I activated a different app Mac window on the iPad. I need to check the SwitchResX options on this. Probably need it to change to Luna display settings, but NOT change back as long as that app is active, even if it isn't the prime focus.
I think the Luna Display is a very clever device, but if I were to compare it to the TextBlade, they aren't even close. The TextBlade is fantastic in almost every situation I'd use a keyboard with only tiny special cases where something else may be better. The Luna display is fantastic is special cases, but only for those cases. Since it doesn't cost much, it's still worth it for me to have it for those special cases.
