What would I like to see? Macs with upgradable RAM and storage. Actually, I can buy the argument about RAM not upgradable, because you can't do that in a Raspberry Pi. However, the M1 Mac Mini I use at work has run out of storage and it's driving me up the wall that I can't just bung a bigger SSD in.
What would I really like to see? A general slowdown with the churn of macOS releases, and an emphasis of stability and bug fixes. If I recall correctly, the gap between Tiger, Leopard and Snow Leopard was much longer, and Snow Leopard in particular was famous for its "no new features" tagline, concentrating entirely on improving what we currently have.
What do I expect to see? Basically any Intel Mac that's not the Mac Pro and that you can still purchase from apple.com to be replaced with an Apple Silicon variant. I think that's just the high-end Mac Mini and the 27" iMac now.
