Yep, +1 for iPad Pro and Notability.
It’s one of those very rare occasions where you’ve bought tech to do a thing, and then kept using it rather than reverting to what ever you did before. It really is better than pencil and notebook for my purposes at work – scribbling/sketching, writing notes and recording.
And everything is kept, is sortable, searchable, and shareable. Being able to ping out PDFs of a sketch, and also being able to plug the thing in to a big telly to do ‘co-design’ sessions, is all really good.
Is a bit pricey though.
Edit, it’s worth getting the desktop version of the app too, then whatever you have on your ipad is also available on your big screen, for editing, cutting/pasting into other documents etc.
