It depends hardly on the kind of keyboard/mouse you want. My recommendations, based on workstation I’m keeping at home:

Keyboards

• Logitech K780 (as @[email protected] said)
• Logitech MX Keys (full or mini, if you don’t mind about numpad), this is my top keyboard atm, the one I’m using as developer mostly.
• Logitech G413/G413 TKL (wired, but works nice out of the box, mechanical, perfect for gaming and typing)

Mouses

• Logitech G203 (wired, works nicely on Linux too)
• Logitech M650 Signature (my favourite mouse, actually)
• HP 430 Bluetooth Mouse (works nicely, and does not require dongle because it works throught USB)

Extra

Logitech devices use to have all-in-one dongles, so you only need one for connecting all devices, saving you some USB ports. The unifyied dongle looks like this.

This one is Logitech MX Keys, I’m using it as regular work keyboard (I’m software developer), but too big for jams, so I was thinking about something like MX Keys mini or Logitech Pebble, both TKL and bluetooth. Also a portable 15.6 screen because carrying this Lenovo one would be problematic.

I’m curious about how we ended here but this is the best comment I read today xDD
