You could work with one laptop and one Mac Mini. I've used many KVMs over the years, and they generally work fine to let you switch from one device to another, but they do assume you won't be working on multiple devices simultaneously. I can confirm that the external Magic Keyboard and Magic Trackpad do both work very well, as good as or better than anything integrated into a laptop. And since they charge via USB, you could easily just keep them plugged into the USB ports on the KVM device -- if you were to go that direction. If you want them to feel like a unified single keyboard, then 12 South has you covered with the MagicBridge [2]. I think what you really want is a software KVM solution that lets you share the same keyboard and mouse across multiple machines, each of which is being simultaneously displayed on your screens. Just drag your mouse from one screen to the next and you're suddenly working on the other computer. This is what Universal Control [0] is for. There are alternatives [1] like Barrier or Synapse, but I think UC will probably be the best Mac-native solution in this space.
