I bought a full-size HP keyboard and now I found out it's got these little, tiny keys. It's crazy .... you could never tell from the picture on the box and they never say anything about it. It's nothing anyone would want in my opinion ... so be careful!
I'm using Logitech wireless keyboard + mouse. They have long battery life, are very convenient to use and they are connecting trough Logitech Unifying USB Receiver. So, the keyboard and mouse are functional during boot and in BIOS (exactly like wired keyboard and mouse).
There are combo sets (keyboard + mouse). I'm using K520 keyboard and MX Master 2S mouse. There are chipper and also well working combinations.
My HP keyboard was on sale, so it didn't cost much. Apparently, it's so hard to get a computer with the parts shortage, they have way too many keyboards on hand to sell !
I agree with Leon. I use only Logitech. I have Wired - NetPlay and (my favorite) G15 Gaming (multiple V1's and one V2 (a gift from Doc)) - and Wireless - multiple K250's and K400's. I also have some MK270 Wireless Keyboard/Mouse combo kits as well.
Anything Logitech seems to be good. I have Logitech speakers ... the audio from my NUC is amazing! Better than my regular stereo, TV and car!
