I have the ‘22 iPad Air. It’s amazing, but it’s not a computer in the most frustrating ways, despite its potential to be so. The iPadOS 17 updates coming down the pike are really neat and bring it closer to matching your use-case, but it’s very infuriating when there’s something super simple to do in a desktop OS that takes a lot longer than or is simply impossible on iPadOS.
As for the Chromebook- yes! You can make yourself a magic/smart mirror. I did this with an old laptop during the initial COVID lockdown. You’ll need a shadow box, the laptop, the mirror glass, software (I think I just used off-the-shelf Rainmeter), mounting hardware, and accessories (I didn’t make mine touch-screen, so there’s a wireless keyboard and mic for Alexa integration). You can find numerous guides online for this, and numerous sites that sell custom-cut one-way mirror glass. I think all-told (buying mounting hardware, frame, spray paint, mirror glass, and accessories) it came out to about $175, but that was with a fairly big glass panel (it’s the largest single cost in these projects, and my laptop that I was using for this was 16”, so I needed something like 28”x18” glass).
