Good to reconfirm I guess. I really wanted the Apple Silicon Macbook but will have to wait for a while now. Windows in the mean time.
Ryzen would be similar to Intel just far better at everything (performance, cooling, noise, battery, igpu etc). ARM brings genuine new experiences as well as the rest. It also brings iOS appstore to Macs and even better per watt performance. Apple's software will be very strong. The iPad is much nicer at a lot of stuff than Mac Os so its going to be very good I assume.
Given per watt performance is being said so much, I have a feeling these first ARM might not match up to Ryzen on pure performance currently (despite being 5nm) but its looking really good otherwise!
