Whilst it might have some niche use cases, there are other ways to achieve much of the same functionality, often with additional advantages.
- The MacBook screen can be mirrored to a tablet with 3rd party software.
- Individual tool pallets on macOS can be controlled from an iOS app, depending upon the software.
- For extended use, the location of a Macbook's screen isn't ideal
- For for hand and finger gestures correlating to certain parts of the screen (for presentrations, for example) a Leap Motion controller could be suitable.
- Use a Windows PC instead. This gives less distance between the user's finger / stylus and the pixels, thus reducing parallax error. Also, stylus import will be more nuanced and accurate. The same advantages can also be had by:
- Use a Cintiq touchscreen monitor in conjunction with the MacBook, or a standalone Citiq tablet.
- Use an iPad Pro with stylus
I'm not saying that the AirBar doesn't have a place, but it isn't without competition from existing ways of doing much the same thing. That is why I was surprised to read that a lack of touchscreen was a 'consistent complaint' amongst Mac users. It's also worth noting that the company Modbook - who turned Macbooks into touch screen tablets - hasn't posted any 'News' on their website since November 2015... lack of demand, I assume.
