iPad Pro 12.9" vs. MacBook Air for my needs?

[badlydrawnboy]

I currently have an iMac Pro and M1 MacBook Air. I'm considering replacing my M1 MBA with the new 12.9" iPad Pro.

The main reason is that I do quite a lot of photography, and the 12.9" iPad Pro seems like a perfect mobile photo editing option. I have edited on an 11" iPad Pro with the Apple Pencil in the past, and having a larger and higher contrast screen along with an even faster chip would be amazing.

As I think about this, I'm wondering what (if anything) I would miss by giving up the M1 MacBook Air. I use it for pretty basic stuff:

• Web browsing (Brave/Safari) and email (Spark)
• Productivity (Asana, Things, Google Docs, Calendar, Roam Research, etc.)
• Watching videos, listening to music, etc.

Doesn't seem like there's anything on that list that an iPad Pro couldn't handle. I do wonder about the Magic Keyboard—is it comfortable enough to type on? How does it balance in your lap? Also, the battery life of the M1 MBA seems quite a lot better, though I'm not sure how much that really matters. It's rare that I go more than 8 hours without being able to charge.

I have the iMac Pro at home for anything that requires an actual computer.

Is there anything else I'm not considering that I should be?
