I've got a nice mouse already (Logitech MX Master 3). I don't use a touchpad if I can help it.

The new designs have really good keyboards, better than the pre-butterfly ones IMO.

I have a 14" M1 MacBook Pro. The keyboard is "ok" but not great. It occasionally misses keypresses when I'm typing fast or hit the edge of a key.

Also I never really got on with the keyboard layout. Some things are just better on other platforms like position of hash, usage of meta-keys and discoverability. I find, despite rarely using it, that I can navigate around windows 10 better on a keyboard than I can on a mac.

I mostly use my mac in "desktop mode" with an Apple studio display (that's the most difficult thing to give up) and a TKL Durgod K320 cherry MX red mechanical keyboard so I will reuse the keyboard for "the other platform"
