You might be surprised. I'll be the first to tell you there's a ton of overpriced, silly hype in the keyboard space. Exotic materials, lubes, and switches that have no measurable impact on performance are common. So are extremely detailed and expensive artisan keycaps. It's a collector hobby for many. That's not my thing.

OTOH, there are also some serious gains to be had for professional computer jockeys.

My daily board is just 42 keys, and I absolutely love it. There's a learning curve for sure, but once mastered you're on a new level. For instance, I can access all my standard keys, num now, function keys, and arrows without having to move my hands off the home position. It's brilliant.
