Thanks Toby!
That’s pretty much exactly my use case 
The main benefits of the 11" Pro seem to be:
- 120Hz screen (promotion)
- M1 chip
- 128GB base model
- Better camera (12MP Wide and 10MP Ultra Wide vs 12MP Wide)
- Better front facing camera (TrueDepth Ultra Wide 12MP vs 7MP)
- USB-C Thunderbolt / USB 4 (vs std USB-C)
- Slightly bigger screen (11" vs 10.9")
- Slightly thinner (5.9mm vs 6.1mm)
- (Slightly heavier tho, at 466g vs 458g)
The Air base model is 64GB and if you go to 256GB then it’s not far off the Pro’s price. I think 64GB may be too small. 120Hz screen is meant to be a little nicer with the pencil too.
Air: 64GB - £579
Air: 256GB - £729
Pro: 128GB - £749
So currently I am leaning more towards the Pro as I think 64GB on the Air is just a bit too small - what size is yours?
