My colleagues have purchased keyboards that are split, or short, or different colours, or contains flashing strobe lights — but I just one that is comfortable, helps me be accurate and preferably wired.
I can't figure out what is good keyboard, I can realise adding multicolour leds doesn't help but for the rest I'm not sure.
Budget <$1000 (I'm not looking for a $1000 keyboard just this is the max it's worth to me in productivity, if a $10 keyboard is good I'm happy with that)
I think you'll find that different people will have different preferences and you're best bet is to go and try them yourself.
Personally, I use the Logitech MX Keys (approx $200) paired with the MX Master 3 mouse ($149) for work daily and love it.
