Politely: I won't install an Adobe Air app unless forced to by me employer. Maybe that's how this will work, but Air is always a drag in my personal experience.
Because it's Yet Another Runtime that I Don't Want to Have to Install and Maintain.
I have yet to see an AIR application that is truly cross-platform functional. They run, but that doesn't mean that I want to spend time in them.
I hadn't heard of hall.com before this post, but while I appreciate that (a) you've done this out of response to your users (good) and (b) you've done this because it's faster than doing something else, (c) I don't install AIR.
These days, I only want .apps that include everything I need inside of the app bundle and don't require external installations. (I say this as someone shipping a USB stick with an app that, to apply an update of the app on the stick from the Mac, you have to have a driver installed. I don't want that driver, but I have to. Can't stand it.)
