If you decide on a Macbook, don't even consider anything lower/older than the 2020 M1 MacBook Air, as that was the first MacBook that used Apple's own chips rather than Intel. It's hard to describe with words how much better Apple's own chips are compared to the older Intel MacBooks. You can get a used 2020 M1 MacBook Air off of eBay for around £600, sometimes even less if you get lucky. While this isn't cheap, its only half as expensive as the newer M2 models and it will still last you at the very least 5-7 years before it becomes outdated. In my opinion it's definitely worth the investment. As it has no fans in it, it will be completely silent, but it will also not overheat as the Apple M1 chip is so power efficient. I've heard that some people can get multiple days worth of battery life out of a full charge as well. The 2020 model is much better value than the newest models, especially if you get it second hand. Bearing that in mind, it's hard for me to even consider a windows laptop as none that I have seen come close to the ease of use, power, form factor and longevity for the price. I really can't recommend it enough. Another bonus is that all of your current notes from your iPad, assuming you use the Apple Notes app or Google Docs etc, will likely be able to sync with your laptop. The only downside I can find about the MacBook is the storage, but in all honestly I'd just go for the 256gb model, or if you find one that's reasonably priced, a 512gb model, and buy an external SSD or hard drive if you need it as it will save you from spending an arm and a leg on a model with higher storage.
