Personally, I’m of the opinion that 40% boards appeal to the same type of person that loves fiddling with their graphic sliders and driver settings on their computer games, marvels at the beauty, takes screenshots, posts them, then shuts off the game.
I respect that, to some, that is the game.
To me though, my board is in service to my use. I require that all the keys my fingers know, be there in the place where they should be. And that includes the num row. So, no lower than a 60%. I’m not about to retrain my brain for a marginally more compact footprint.
I will admit that I never thought I’d go lower than a TKL and now I’m happy as a clam on a 60%, so I’m probably just stubborn, biased, and crabby on the subject of 40%.
My son has a couple of 40s, and this is a topic of discussion between us. I just don’t get it, but I hear you all, and you’re cool.
