except in specific niches like in digital note taking/drawing, or industrial cases where it becomes a glorified HUD.

The one niche that they’re probably the biggest is the “I just need a public facing web browser in this spot”

Its really hard to beat a locked down iPad for that usecase, both from a financial perspective (~$250 hardware cost for a lowest-tier iPad was the price I was seeing when ordering and provisioning them for this usecase) and from a management perspective (join it to the MDM and by nature of being an iPad, even if they get out of the browser window its really hard to cause trouble, basically 0 malware risk and iOS has far less obtrusive updates than Windows) plus from a support perspective you can simply walk users through rebooting them and swap the hardware if it needs more than a reboot
