I’ve owned tablets from 7” to 11” (+ a 13” iPad Pro for 2 weeks) and for my usecases and I’m happiest with the 11” of the OnePad Plus I have now. I’ve used most of them as pure consumption devices though I’ve used a Pixel C (from 2016ish) as a laptop replacement for 3 months because my BTO laptop config didn’t get shipped sooner. With a keyboard you can do a lot with them nowadays. The latest iPad OS updates seem very impressive if you’re okay with that ecosystem, though I’m not. If I had to, I’d mostly consider the latest gen OnePlus Pad. No complaints about mine, except for somewhat delayed major Android updates because of their custom skin but the skin itself is nice.
I also own a Daylight Computer DC-1 and I think I could get some work done on it but I use it mainly as an offline reading device since abandoning my Kindle. Their Android is kinda old though and shipping updates takes quite a while because they seem to have a small team.
If my Macbook Air wasn’t as powerful and lightweight, I’d consider paying the tablet with a keyboard again. With Android 16 the desktop mode + external display support will also become much much better.
