I love the iPad for its stylus, it’s a great device for brainstorming even with just notes. I wish there was more creative software they took advantage of the form factor however, like a touch/stylus based programming environment.
It is marketed to be more than a drawing device tho. It fails at anything but being a glorified scratchpad. Very narrow usefulness.
I got the first iPad (2016?) with pencil, for 400€, I think. It still does completely fulfill my needs for brainstorming. For anything else, the app ecosystem and locked down system are useless.
