I've wanted one for gaming on the go with the Switch and Steam Deck, but couldn't really justify the purchase.
...but if I can pretend I use it as a second monitor for work, then it's OK! :D

The iPad and Mac have Sidecar which lets you use the iPad wired/wirelessly as an additional display for the Mac but it's so damn flaky that I gave up and got the portable monitor.
I do carry a cheap HDMI->USB adapter (Elgato Cam Link knock-off) which lets me use my Macbook as a monitor for things like Raspberry Pi's but not sure what the capture rate is.
